It will not be a disappointment as long as you have your expectations properly set. Inspiration is an older ship that isn't as "pretty" as the Enchantment. Carnival offers a different cruise experience than does RCCL. I like both lines, and personally think Carnival has better buffet choices (great pizza and deli), as well as larger standard cabins. To me the dining room food is about equal. The Fantasy-class ships are not especially appealing to me, but they offer a fine cruise experience. Actually my favorite Carnival ship is the Holiday - which is smaller than the Inspiration and older too. Yet my favorite RCCL ship is the Freedom Of The Seas - about 4 times the size of Holiday. Remember what I said - if your expectations are properly set you will have a fine time.
