Well, out of the ones I have stayed at, we liked PO-R Alligator Bayou section, building 14, the best. We love the theming, the landscaping, the pool, the foodcourt, the general store, and the whole laid back atmosphere. The boat to DTD is a nice added touch, too!
Although we have never stayed there, we have visited, our least favorite would be CSR. It is too big and spread out. Seems like it is trying to hard to be a deluxe, and doesn't have the Disney feel, as it seems to cater to the business crowd that use the convention facilities.
We also feel that the lack of a 2nd sink in the room is a big drawback.
We also like CBR, the only drawback to that being if you happen to be staying at one of the remote ends, such as Barbado, or Trinidad South. That is just not very convenient to anything.
We are staying at PO-FQ this fall, and hope that it too will be a favorite. It is more compact in size, and from the pictures, looks like the theming is very well done.
