I did not like CBR much when I stayed there when I was a little kid, and I liked it even less when I stayed there last month!
Here's my honest opinion about CBR. It is such an intensely boring theme to me. The coolest parts about the Caribbean are the beaches and the nature, NOT the buildings, LOL! You can't really re-create a real Caribbean beach, so I just find it to be very lame. Unless you have young kids who really like pirates, I'd definitely choose any moderate over CBR.
Also, even though I don't use them, CBR has no elevators. I think that could be a major problem depending on how much luggage someone has with them, how old they are, how tired they are, or if they might have a disability.
Additionally, I think that a lot of the hotel buildings (excluding OPR) look kind of like apartments in a coastal suburb. Not that that's bad... But compared to the themes of other Disney moderate resort buildings, it's very boring.
