For the price of a mid aft inside cabin on princess for a 7 night cruise in the spring, i can go on an ocean view midship 6 night cruise on celebrity. I thought if food was better or substantial differences i'd go for celebrity. However, given itinerary is better on princess i am inclined to go with them. I know the inside rooms on princess aren't nice and i did really like my little couch on royal caribbean but oh well. Some people seem to think the cabins on princess are well designed. I'll think about it though as the fall is supposed to be a less rough time for the pacific coastals.
