From check-in
to your first horizon.
Your step-by-step guide to preparing, boarding, and settling into Mystery School At Sea.
Before you check in
Every traveler—including presenters, staff, and vendors—must complete Celebrity’s cruise check-in. Mystery School event registration is a separate step.
Celebrity Millennium · Singapore departure: January 27, 2028 · Benoa, Bali disembarkation: February 10, 2028.
Have these details ready
- Full legal names and dates of birth for everyone in your reservation.
- Your Celebrity confirmation number from the booking invoice.
- Passport and any required immigration documents, including document numbers and expiry dates.
- Home address, phone number, and an emergency contact’s name and phone number.
- A payment method for your onboard expense account.

Share this preparation list with your roommates or travel companions. Check that the name on your booking and boarding documents matches your passport; ask your travel agent to arrange corrections.
Online check-in, step by step
Celebrity currently describes app check-in as opening 45 days before sailing. The exact 2028 availability, deadlines, and terminal arrival slots must be confirmed in your account. The old February/March 2026 window does not apply.
- Open the Celebrity app or website. Sign in and link your reservation if needed.
- Confirm your travel details. Enter the requested personal and passport information. The app may let you scan your passport and take your security photo.
- Select an available arrival appointment. Follow the choices shown for your sailing. An earlier appointment is subject to availability, not guaranteed by completing check-in first.
- Set up your onboard account and complete all remaining prompts for each guest.
- Save your Xpress Pass. Keep a printed copy or an offline phone copy; use a digital wallet if the app offers it. Do not depend on terminal internet.
- Print your cruise luggage tags when available and follow the attachment instructions.
Celebrity app guide · Online check-in guidance
App or computer—which should I use?
The app can simplify passport scanning, photo upload, and access to your boarding pass. A computer is also an option. Available steps and their order may change, so follow the current prompts rather than an older video’s exact screen sequence.
Optional purchases before you sail
Your account may offer Wi-Fi, drinks, specialty dining, spa treatments, and other add-ons. Compare prices and your group inclusions before buying; savings and package availability are not guaranteed.
Travel documents & insurance
You are responsible for complete immigration information and the documents required for your nationality, route, and transit countries. This voyage visits Singapore, Thailand, Malaysia, and Indonesia.
- Confirm passport validity and blank-page requirements.
- Check visas, arrival declarations, and any other entry requirements with the relevant official authorities and Celebrity.
- Review requirements again closer to departure; rules can change before 2028.
- Carry original required documents in your hand luggage.
The previous Greece/Turkey and European ETIAS guidance is not the guidance for this sailing.
Celebrity travel-document guidance ↗Review your insurance
Ask your insurer about overseas medical care, emergency evacuation, cancellation, delays, and baggage protection. Do not assume your domestic health policy covers a cruise abroad. Discuss suitable coverage and any exclusions with your insurer or travel adviser.
The earlier guide lists Diane at Legendary World Travel, +1 336-749-1219, for travel assistance. Confirm current 2028 service arrangements with our team.
Boarding day in Singapore
Embarkation is Thursday, January 27, 2028. Use the terminal address and arrival appointment on your final cruise documents; do not use the former Athens/Piraeus instructions.
- Arrive at the designated terminal at your assigned time, allowing for traffic and document checks.
- Follow staff directions for passenger and luggage drop-off. Porters handle tagged checked bags.
- Keep your passport, required entry documents, Xpress Pass, payment card, medications, valuables, and immediate essentials with you.
- Complete document verification and security screening.
- Complete any health questionnaire or other boarding requirements when prompted by Celebrity.
Checked bags arrive separately at your cabin. Pack enough in your carry-on to be comfortable while waiting.
Use the carry-on packing checklist ↗Your first hours aboard
Settle in
Follow the crew’s announcement about when cabins are ready and when you may drop off bags. Check the Celebrity app, stateroom information, and daily program for opening hours, ship orientation, activities, and dining.
Find lunch & plan your day
Consult the current daily program for open venues and any cabin-category dining arrangements. Some specialty dining, spa appointments, and fitness activities may require reservations or an extra charge. The old Infinity venue/deck list should not be used as a Millennium boarding-day schedule.
Complete the mandatory safety drill
Every guest must follow the ship’s muster instructions. Review the assigned safety information through the app or stateroom television where available, then report to the designated muster station as instructed. Ask the crew for help if you cannot use the digital process.
Carry your SeaPass when leaving and returning to the ship, along with the identification required for that port. Always follow the announced ship time and all-aboard deadline.
Mystery School group arrangements
The earlier guide’s Conference Center location, 1:30–3:00 PM check-in, 4:00 PM orientation, 5:30 PM photograph, and 6:15 PM dinner were for the previous voyage. They are not confirmed appointments for 2028.
Seminar check-in
Attendees, presenters, staff, and vendors should watch for the separate Mystery School check-in instructions. This is where program materials, event identification, and any applicable excursion or special-event tickets will be explained or distributed. Keep your event identification available for access to group sessions.
Welcome meeting & group photograph
Our welcome orientation will explain the group’s logistics. Meeting time, location, and group-photo arrangements will be announced in the final program.
Dining together
Group dining time, venue, and seating arrangements will be confirmed. Follow the final instructions rather than assuming that a printed table number is optional. You may also explore other ship dining options, subject to their hours and charges.
Presenter products & private sessions
Presenters may offer books, recordings, other products, or private sessions. These are separate from Celebrity’s onboard account; confirm payment methods directly with the presenter. Ship ATMs may charge fees in addition to your bank’s charges.
Explore the provisional presenter lineup ↗SeaPass, payments & gratuities
Your SeaPass helps identify you aboard, access your cabin, and charge eligible onboard purchases to your account. Keep it secure and follow the crew’s instructions when going ashore.
Your onboard account
Set up the payment method accepted for your reservation. Review charges during the voyage and resolve discrepancies with Guest Relations before departure. Credit, debit, and cash arrangements can have different authorization or settlement rules—confirm the current options with Celebrity.
Gratuities & service charges
Confirm your 2028 group package and invoice to see whether gratuities are prepaid. The earlier page’s daily dollar amounts are not a quote for this voyage. Drinks, spa services, and other purchases may carry additional service charges; review the terms shown before purchasing.
Optional extra tipping is a personal choice. Ask the travel team if you are unsure which charges are included.
Current Celebrity account and gratuity FAQs ↗Health, families & accessibility
Health preparation & vaccinations
Review your travel summary and discuss the route with a qualified travel-health professional well before departure. Follow Celebrity’s current health requirements and complete any required questionnaire when it becomes available.
For seasickness concerns, ask your clinician or pharmacist about options appropriate for you. This is especially important during pregnancy or when taking other medication.
Traveling with children
Confirm the minimum infant age for this specific itinerary before booking. Celebrity commonly requires at least six months, with stricter requirements on some voyages. Ask about the current Millennium youth program, age groups, toilet-training requirements, supervision, hours, and any fees.
The previous guide described parent-supervised Toddler Time, Camp at Sea for ages 3–12, and optional supervised parties. Confirm the offerings for 2028 rather than relying on those earlier hours.
Pregnancy
Celebrity’s current policy does not permit sailing if you will reach the 24th week of pregnancy during the cruise or cruise tour. Confirm eligibility directly with Celebrity and discuss your travel plans with your clinician. Shipboard medical facilities are limited.
Mobility, accessible rooms & transfers
Discuss your requirements with the travel team before booking. Request accessible cabin features and airport/port transfers early; availability and service outside the U.S. can vary.
Standard cabins may have narrow doorways, bathroom thresholds, or bathing arrangements that are unsuitable for a mobility device. Confirm measurements and storage/charging arrangements; devices must not obstruct corridors.
Request boarding and departure assistance in advance and again at the pier. Waiting times may occur, and crew assistance has safety limits.
Tender ports & going ashore
Gangways, small tender boats, tides, weather, and shore facilities can limit access. Some ports may not be accessible with a wheelchair or scooter even when you can board the ship.
Do not assume crew can lift a guest or mobility device. Discuss assistance, transfer ability, and any companion needs with Celebrity before booking. The captain and crew make the final safety decision on boarding and tender access. Ask your travel adviser about the applicable terms if a port cannot be accessed.

Onboard policies
Smoking & vaping
Use only the ship’s designated smoking areas. Smoking is not permitted in cabins or on cabin balconies, and restrictions apply throughout the ship. Ask Guest Relations about the designated areas and current tobacco/vaping rules. Never throw smoking materials overboard.
Keep the voyage comfortable for everyone
Follow crew instructions, dining dress codes, and the health and safety rules in your booking documents. Check the packing guide before bringing electrical items, beverages, or other restricted goods.
