My DD is also a fish.
Here is my opinion of the pools of the resorts I have stayed at by category:
Deluxe Resorts
Beach Club -- SAB, enough said
Boardwalk Villas -- Big slide!
Wilderness Lodge -- nice pool area, nice slide, deep water
Swan/Dolphin Grotto Pool -- very nice pool area
AKL -- OK slide, relaxing pool area.
Polynesian -- OK slide, nice view

Contemporary (I agree, it's boring!)
* Note, I think Grand Floridean would be before the CR, but I have never stayed there.
Home Away From Home Resorts
(Rent DVC points)
Beach Club Villas
Boardwalk Villas
Villas at Wilderness Lodge
Old Key West -- I have not been back since the pool rehab.
* Note, SSR may be better than OKW, but I have not stayed there.
Moderate Resorts
CSR -- Interesting pool area, ok slide, it's cool in the falls
CBR -- I thought this pool was boring
POFQ (babyish, ok for little kids)
* Note, I think PO-R might be better than CBR, but I have never been there
Value Resorts -- All pretty boring. No slide, no hot tub.
Pop Century
AS SPorts
AS Music
* Note, AS Movies is probably better than AS Sports, but I have never stayed there.
