I have done 50+ hours of net research on the STR near Disney places. There are SO many for example (Solterra, Solara, Solana, Sonoma) and that's just the So...and then subdivisions within some.
Many developments look like they could expand as well. In general I’ve found that new builds are least expensive, limited/hard to get, the better amenity places like Windsor Hills are a bit dated homes, newer places have smaller amenities. I’ve been focusing on 6-14 bedroom places. Encore has nice homes and good amenities, but you may have to use their own management company. Some gated communities have complaints of break ins, some people have horror stories about the new construction.
Although in theory this area sounds like a slam dunk (popular attractions nearby, weather decent year round, allowance of STR in gated communities), perhaps so many people are thinking this it's causing problems. 15-20 years ago Windsor Hills places were selling for about what they are now.
If anyone has seriously looked into the STR area here, I'd be interested to hear your thoughts. I am already working with a Realtor.
