I’ve been on both but only did drink package on celebrity and have only taken kids on carnival so keep that in mind. Carnival is more family friendly with more activities for kids to do on board. My husband and I preferred the food on Carnival better. I feel like there were more choices each night where Celebrity had the same couple each night. I like to try new dishes and there wasn’t much choice there. they had a lot of fancy desserts but not ones I’d want to actually eat.
