BWI for me. Stayed there, had an EPCOT view with an amazing view of Illuminations and the Eiffel Tower and Spaceship Earth from the balcony. It was quiet, and the room was large and cheerful!
The room service was quite reasonable and generous, the location was unbeatable, and the Boardwalk Bakery and Spoodles Pizza Window were out of this world!
I've heard awesome things about Stormalong Bay, but the BWI pool suited me fine, and wasn't at all crowded!
