We have done 32 cruises and this was our first Princess cruise. From beginning to end we enjoyed the cruise. We were on deck 12.
The ship is new and beautifully appointed. The balcony cabins are a bit small but not uncomfortable. The balcony is fine for two people. The bathroom is smaller then we are used to. The shower, for a big/tall guy, is very tricky. Our cabin steward Michael was over the top great. Professional, personable and when you went to breakfast the cabin was made up perfectly when you returned after breakfast. As we spend so little time in the cabin these issues weren't that bad but a bit larger would have been better.
Entertainment: Like so many other cruise ships the entertainment is either just ok or a waste of time. In the past several years many cruise lines are really cutting back on quality entertainment and Princess is no exception. Many high school productions are better.
