We've been wanting to try Princess after having done three Celebrity and two RCI cruises.
Pros: Fastest embarkation and debarkation we have ever experienced, and the stateroom was ready upon boarding at 12:30.
Stateroom: We had Mini-suite E721 which was very spacious with a very comfortable bed and covered balcony. Decor is somewhat dated, couch sat very low and not comfortable. Nice layout with tons of storage. Wonderful room steward although, initially, there was a lot of dusty/dirty surfaces but our room steward apologized and cleaned it up.

We went to the beach across the street from the ship - very nice
Stone Island on our own.
