Hi Brian,
I'm not sure what your budget is. However, since you mentioned that your little girls love the pool, I want to highly recommend the
Beach Club Resort. This is one of my absolute favorites. The pool, "Stormalong Bay" is incredible. It has a sand bottom, a ship-wreck slide, whirling waters, a lazy river and more. It's like having your own little water park at the Resort. My children all love this Resort, including my 6 & 8 year old daughters.
In addition, the Beach Club is walking distance to Epcot and a relaxing boat ride from Hollywood Studios.
Hope this helps and have a wonderful vacation,
Kaylene
