I go to WDW several times a year and have pretty much settled on the moderates as my favorites. I'd rank them:
#1. CSR-consistently has the best bus service, most comfortable beds, best pool, longest pool slide, biggest hot tub on property, only moderate to have a health club/spa/beauty salon, has the most adult feel. We love the beautiful fountains in the Casita section and the lovely white sand beaches and hammocks in the Cabanas. Not a fan of the Rancho section though. If you happen to be on the
DDP the Pepper Market is a very good deal--breakfast and lunch are buffets but still a counter service credit.
#2. POFQ-smallest resort on property so no room is very far from anything, love the boat to DTD and Elliott Dyson's show in the lounge. The pool is a little kiddish though and they don't have a quiet pool. They share a bus with PORS, but POFQ is the first stop so you pretty much always get a seat in the mornings.
#3. PORS-beautiful resort, love the boat to DTD, love their food court and just the general laid back feeling of the resort. We also love Ye Haw Bob's show in the lounge.
#4. CBR--not a big fan--the resort just feels alot bigger than the other three, housekeeping seems to always stink, have always had bad luck with the bus service, not a fan of their food court or TS restaurant, the main pool and hot tubs always seem to be jam packed. They are also the only moderate that won't have queen size beds, just full size. It is a very pretty resort though.
