I've stayed at all of the moderates (POR multiple times, POFQ once, CSR twice, and CBR three times). I enjoyed all of them, and would be happy at any of them, but much prefer POR. I love the meandering pathways, the food court has a nice decor with plenty of seating, we never miss Bob Jacksons show at the River Roost, the boat to DD is a great plus -- I don't know, I just love it there.
My least favorite (which is all relative, as I like them all) is CSR. I hated the food court set up - I don't want to wait to be seated at a food court, and I don't want someone refilling my mug - I want to get what I want when I want it. I also find it odd to tip at a food court, like I said, I don't want all of the "extras" that to me are annoyances, I just want to do my own thing. Also, and for my family this is kind of a deal breaker with this resort, the food court is not run by Disney so they do not have to be as great with allergy meals. My husband and son need to eat gluten free, and at all of the disney owned food courts a chef will always come out, talk to us, and give us tons of GF options. When we contacted Disney about this before one of our trips, they recommended that we mainly stick with disney run restraunts (this mainly applied to Epcot, but it would also apply here). I have to admit we haven't tried it, I stayed there prior to having this need, but we would be in a real bind if we tried eating there and found they were not as accommodating. I also just didn't prefer the theme as much, just not as much to my taste. That is purely personal, I know plenty of people prefer it. I do like that they have massages and a health club, unlike the other moderates.
