I really enjoy POR. It is sprawling, but the landscaping is lovely, and I really like southern feel. I chose to stay in an Alligator Bayou room and was enamored with the log beds, "quilts," and song of the south shower curtain! And for some reason, I really LOVE the food court there. I can't explain that in the least. Finally, I like that you can grab a boat to DTD or book a carriage ride. Although I'd prefer to be within walking distance from a park, no moderate offers that option making POR's and POFQ's proximity to DTD a winner. POR's two sections--alligator bayou and the mansions--couldn't be more different in character, landscaping, decor, and general feel, so be sure to look at some pics before you book.
My only qualm with POR is that it often shares a bus route with POFQ, meaning you can go through up to 5 stops to get to your hotel room or to the park. Worse, POR is always the last to be picked up and the last to be dropped off, so you're often forced to stand on packed busses.
CSR is my favorite moderate, mostly because of the numerous hammocks, ever-present margaritas, and the wide-open feel of the place. Also, I've stayed there several times and have always had an excellent experience with staff going out of their way to make my stay a great one. The main pool and quiet pools are fantastic, though I've been seeing a lot of non-guests in the pool area lately and wish Disney would figure out a way to monitor that. My complaint here is the food court; it just couldn't be worse, from food quality to ordering/eating process. It's not a disney-run joint, which always signals a problem.
I've only visited CBR, and was unimpressed with the pools and twisty-turny layout of the place. Rooms seemed smaller as well, which may have just been the layout.
I can say very little about POFQ as I have really only walked around the area, but it's quite nice and would be a great pick for anyone with mobility problems (it's small). I didn't love the "city" feel I got from it, however (same way I feel about the Casitas section of Coronado Springs), and prefer to leave the streets and sidewalks at home when I'm on vacation.
