My parents retired to Celebration and I visited annually. I haven't played the Celebration course in probably 15-20 years, but it was and likely still is a wonderful course. I'd played Osprey Ridge, the Tom Fazio course mentioned above, a few years earlier. Of the two, I much preferred Celebration. Orange County is nice as well. My favorite "close to Disney" course though was Falcon's Fire.
All good options if you're willing and able to travel a few miles, which the OP indicated wasn't possible. Personally, I'd reconsider that limitation.
