I liked the MUTS, and some of the trivia games, and enjoyed the (pricey!) spa. I was upset to realize the theater show was PG-13 as I sat there with my children, we had to get up and walk out. The comic was good and we were very sorry we missed seeing the 2nd one, I guess he was to have boarded in Cozumel? The whole week's entertainment was thrown off, so we missed things and were generally unsatisfied with the shows.
The last morning the water was cut off without warning while I was half done with my shower. And then were were hassled by Homeland Security about our lack of passports after we'd been assured by Princess that we didn't need them, the birth certificates would be fine. Sure, they were "fine" but the homeland security guy said our names would now be on the warning list and if we went again without them we could have to pay fines.
I don't think I'm generally a crank or that I have lofty expectations, but I'm really happy we got a significant discount on the cruise (and nice cabin upgrades, we'd paid for BF and got BB) because I felt the value was much less than what I expected. We're not likely to cruise again anytime soon.
