Bottom Line: Fun Cruise. Positives out-weigh negatives by a large margin. I would gladly recommend Star Princess to the Carib to most folks.
Our history: My wife and I are mid-fifties veterans of 9 or 10 cruises on four different lines. This was our fifth Princess cruise - - 2 weeks in the Med, 10 days to P. Canal, 10 days to East/South Carib, a South to North Alaskan cruise with some days before and after and now this one. This is really the first 7 day cruise so difficult to compare with the previous four.
General thoughts: I believe you can find someone from every cruise who hated it and someone from the same cruise who loved it. Some of that is due to differences in individual preference; some of it is due to differences in preparation. Kudos to Cruise Critic and those who contribute to the Boards for providing so much information. Because of that info and our previous experience, we always have a great time.
