June 2015 - 11 Night Italy & Greek Isles (Barcelona To Athens) Cruise on Celebrity Equinox
Excellent stops on this cruise - Monaco/Nice, Florence, Santorini and Ephesus were our favorites. The food wasn't any better on Celebrity than it is on Princess. Neither is the service. I believe they're comparable. Celebrity had bigger showers and the rooms were better appointed, but I don't think they're differentiating themselves enough from Princess and I wouldn't pay more for Celebrity.
