We really enjoyed the Pacific Princess, it is definitely our favorite Princess ship. The ship size is perfect. It's small and intimate and there was never a wait for anything. Embarking was easy, disembarking was easy, tendering was easy. It never takes long to get anywhere. The ship has recently been refurbished and it feels new. Service onboard was fantastic, as well as the food.
The only down side to a small ship is less onboard activities. However, that does not matter to us since we tend to choose port-intensive itineraries and spend all of our time on the ship just relaxing.
For those not familiar with Princess, be aware that it is a slow and calm atmosphere. We were the youngest people on the ship at 32 and 45 years of age. We have no problem with this and made plenty of new friends with different generations.
