If you are looking at I-Drive area and the other theme parks then I'd suggest staying on the East side of Disney. We stay on Cumbrian Lakes which is off Poinicana Blvd and it takes about 10 mins to Disney, 10 mins to the bottom of I-Drive, 15 mins to Sea World, 20 mins to Universal.
I believe there are other communities off Poinciana Blvd.
