We haven't stayed there but Windsor Hills does seem to be one of the more popular resorts on the main Orlando Hotels & Attractions board. It has all different types of accommodation - condos, townhomes and then villas (all of which are detached homes I believe).
We had a look round in back in November and it is a really big development and it looks like there may still be an area they are selling (saw a sales office). The reviews do tend to be good though.
