1. Email your request to
[email protected] Include both reservation numbers, ship and sail date. Also mention if you want a table specifically for 4 people (or however many). Note that they usually do not start dining room setup plans until about 50 days before sail date. However, send your email now. They will reply saying to contact them again at the later date, but now you will have a contact name.
2. You can also call customer service at 800-526-9723 and have them note your reservation.
3. A third way is to contact RCL through Facebook Messenger--they usually reply within a few minutes.
4. Another thing to keep in mind is that if one or either of your cruise reservations were made through a travel agent, I believe that the agent has to handle this type of change for you... hopefully others here can confirm if that is true or not. But email them anyway--nothing to lose by trying.
AND, welcome back @hayley_bopp..we missed you!!
I hope it all works out for you, good luck and happy sailing.
