The problem with google earth (or any of the aerial photo sites) is that they still show Windsor Hills Resort from when it was an empty field 2 years ago! lol... so you're not going to see much in terms of what's there today. Keep in mind it's all brand new, just built in 2005.
The aerial / satellite photo you refer to on the Windsorhillsrent.com website IS accurate in terms of the resort's location...they just went and put a "star" where the other sites will show you an empty field!
The mapquest.com picture is a lot better, you can at least see there's streets / etc... interestingly, you can see that it was taken during early construction 2005, since a few homes / lots can be seen but much of it is still vacant. You can see where the townhomes are being built and the condos / clubhouse, for instance!
In 4 short days I'll be heading there.... YAY!
