Yes you have to go to the same place each night. The upper level of the mid-ship dining room is designated any time dining. They check your cabin number on the computer so only the people who are supposed to be there are seated. Only one time did we have to wait and that was for a table for two. It was a short wait. Did not really notice any difference from traditional dining and it was nice to have different people at the table. As for the wait staff everything was great. We did not at all miss having the same waiters or table mates. It worked well for us. We will continue to use anytime dining.
