Royal Caribbean tries their best to accommodate the dining arrangement for all their guest. However, there is a protocol. Requests are taken and giving to the appropriate staff on the ship. You can request a seating time and the table size through your travel agent, or when you book a cruise on line. You're not guaranteeded to get just what you want, that's why they make changes the first couple of days on the cruise. I don't put much thought into worry over dining provisions--I haven't been disappointed yet.
