This is our second cruise and we choose Carnival again because we liked our fist cruise on Valor. We know Inspiration was relatively older so we set out expectation very low - clean cabin, average food and some quiet time.
I can't give a full review to this ship and its services because our experiences will tell you it is not needed.
Cabin - Dirty, period. The bathroom had sewage smell, called for repair/clean up twice, never fixed. Our son dropped his toy under our bed so he used a stick trying to get it out, he got the toy out, as well an opened condom package, a piece of chipped toe nail and something else disgusting.
