This was our first Princess cruise. (We have cruised other lines.) I expected Princess to surpass my experiences, but unfortunately that did not happen.
The ship is beautiful, and we have no issues relative to our stateroom. The stewards were very responsive to our needs. Other than the first day, we didn't have any issue with the elevators. You definitely use them a lot since the dining areas and entertainment are on the lower decks, and the pool, fitness, and buffet dining are on the upper decks with stateroom only decks in between.
There simply was not enough to do on the ship. My husband and I like to have some other activities besides laying beside the pool all day. They have a few token game shows thrown in during the afternoons as well as the usual art and jewelry sales. That's it.
