We sailed on Celebrity Summit last year and were super impressed, so were worried about being disappointed with the Dawn Princess. We were very impressed and had a great vacation.
Service- everyone was very friendly and helpful, good attitudes.
Food- excellent in dining room, very good buffet. We were happy the buffet was open 24 hours so we could always grab a snack when we were hungry, rather than just burgers or pizza during off hours like Celebrity had. We had anytime dining and most servers were great- the one night we had a dud we just asked for a new table the next night.
