We have rented a townhouse in Windsor Hills in the past, as well as one in Windsor Palms, in the fall, always through vrbo.com. The rates were amazing, for 3 bdrm, each with a bathroom, kitchen dining area, livingroom and small private pool. Nothing fancy, but completely equipped and very comfortable.
The resorts were both immaculate, with friendly gatekeepers, and lovely common areas. Ten of us are leaving on Monday (YAAAAAAY!) for a 10 day stay in a 5 br/5bath house in Windsor Hills. It is just a bit closer to WDW and the recreation areas offer more for children who too young to spend 12 - 18 hrs in a park. I will subscribe to this thread and provide a review of our house when we return. Again... utterly amazing rate... we are paying less per night for the whole house than we would for a single room in a Moderate resort, and we seem to be as close (maybe closer) to the Magic Kingdom than some Disney resorts.
