We have sailed on Royal Caribbean, Celebrity, and Norwegian, and wanted to try out Princess with this 3-day cruise. My review will mostly compare this ship to others we have been on.
Embarkation was not pleasant. I'm not sure whether this relates more to the port or the cruise line. We took a taxi directly from the airport to the port. It was a little early; we arrived around 10am. Did not board the ship until around noon. Once they opened the doors, there were several bottleneck areas that were poorly managed by port workers shouting out what to do next. Lots of "hurry up and wait."
I like that you can bring a bottle of wine onboard without a corkage fee. This is a unique benefit that we've only encountered before on Celebrity.
