Only 2 people you should not have to waite, all depends who else wants to eat at the same time you do. If you eat at different times you can ask for the same waiters but their area may be full.
We tried ATD 2 times and now we went back to TD we didn't care for it. Everybody is different. We like having the same waiters and time. Just something we got used to and like it that way. We go to the steakhouse 2 times each cruise and do a night on the lido if we don't feel like getting changed for dinner or the menu don't really turn us on.
