We really like Boardwalk Villas not only because of their proximity to Epcot but because of the nightlife on the Boardwalk itself as well as places like Jellyrolls! They also have boat rental available from the Yacht Club marina as well as specialty cruises and surrey rentals as well.
If you like a laid back place to head in the evening our second choice would be Old Key West. Not only because of the larger room size but because the Hospitality House area pool/restaurant/store is a nice place to congregate. The availability of boat rentals, bike rentals and boat transportation to DTD is a big plus too.
