Windsor Hills has 2 bedroom and 3 bedroom condos, 3 bedroom townhomes (that have a small splash pool), and 3 to 6 bedroom homes. Over the years we have stayed at all 3. For our family of 5 the townhomes have consistently worked best. Condos are the cheapest, most expensive are the homes. Added costs can be pool heat.
As far as concrete numbers I actually happen to have an example from this week. I am less than pleased with the whole resort parking nonsense so on principal decided to look around for our upcoming May trip. We have a bounceback booked for a stay at CBR middle of May. For one room at CBR 6 nights on the bounceback it is $1100. I contacted a townhome I really like at WH and she quoted me $850. My rate was a little less because we have stayed before. That is not a huge difference in cost obviously, but it is an experience that is hard to compare. In fact for us, it is a huge savings because if onsite now with 5 of us my husband always wants 2 rooms and not just one. With the townhome you have your own pool, full kitchen, 3 bedrooms, washer and dryer. Another option, Vacation Strategy with WBC was brought up too on this thread. I have never tried it as we usually our on site or Disney, but their quote for those 6 nights for a 2 bedroom was $1350.
Hope that helps. Let me know if you have other questions!
