I'm with Irish Shark - Personal Choice all the way. We went to dinner at a different time everynight. It depended on whether it was a sea day or we came back tired from an excursion, woke up late from a nap or whatever. I have a strong sense of loyalty to Princess but not to the wait staff. I personally liked meeting different staff members everynight. But that's just my opinion : ) Whatever you choose you will have a great time I'm sure.
