We sailed on the Caribbean Princess for our first cruise in 15 years. We found service to be impeccable. Most staff was eager to assist you with anything. Our room steward, Tito, was efficient but not obtrusive. Loved having wine and snacks at Vines. Pool bars were great as well.
One mild disappointment was food offerings at International Cafe. It never changed - ever. So about mid-week, we were sick of the same pastries in the morning (although they do offer one hot sandwich - think Egg McMuffin) and the same sandwiches for a snack. And we weren't overtly impressed with buffet offerings. We didn't avail ourselves of main dining probably as much as we should have, and the food there was pretty good when we did eat there.
Overall, we liked this ship and the cruise experience. Our cabin (mini-suite)showed a tiny bit of wear and tear in bathroom but it was clean. And I saw them replacing carpet in other rooms during the trip. Public spaces were very clean. This cruise is a bit slower pace than our last one, and since there were a lot of ports on this itinerary, we did not participate in cruise activities that much. Shows aren't really my thing but entertainment seemed to be good quality. I recommend Princess and would cruise again with them.
