I'm sure you can on board but probable need to do it first thing. Some just cancel the one package and order the other right now. Your refund for the deluxe package will take about a weeks.
I can see dining times at all three of my upcoming sailings even 500 days out. None are on brilliance but if you click dinning then a particular restaurant it should show up
as @twangster said the system on Quantum is the "complimentary" (and maybe $20 paid) times are opened at 3:00 the day before. Fortunately we were in a suite and had the concierge do the leg work.
That happen to me when I made my reservation last week. Didn’t show up on credit card so called and It didn’t go through somehow. Handed computer to wife and it worked for her ☺️
Hi John, Stacey and I just booked our first Celebrity cruise! Its not till spring 2024 but loved the itinerary to Columbia, the ABC's and Grand Caymen. Cannot wait to see and experience the retreat as compared to CK/SL on Royal.
