About the defenses of Cabana Bay...
I agree, the sample size is too small to draw any conclusions from. Also, the motivations of people who write on TripAdvisor can be questionable. That said, those who come to the defense of some of CBBR's apparent issues by comparing it to a Disney hotel--that's a bit weak. If Universal wants to be a serious alternative to their neighbors, they have to be their own resort, not justify everything by drawing comparisons to Disney. Disney didnt get to be where they are right now by comparing themselves to another theme park resort; they set their own standard.
Its a social phenomenon that people tend to hate something that has drawn a lot of success...if this blind praise of Universal in comparison to Disney is some peoples way of buying into this phenomenon (hating Disney because of its popularity that we dont see as warranted), that doesnt help any arguments for Universal. I saw this happen on the thread with pictures of dirty things at Universal, responses like "I could show you 100 examples worse at Disney", etc. The point is, who cares what they do? If Universal is going to take a step toward being the best destination in Orlando, they have to start comparing themselves to nothing but their own standards.
Cabana Bay may or may not have issues, I dont know because I havent stayed there yet. But when I do, and find any shortcomings or positives, the last thing I will do is compare it to Disney because I dont feel the need to join into this recent groupthink that Universal can do no wrong and Disney comes up short. The best way to evaluate something is to just judge it on its own merits. I wonder if similar issues at a Disney hotel would have had similar reactions on this board (justification), or intense criticism...
