You're going to love it! We had 2 of the best vacations we've had ANYwhere...EVER when we rented a townhome in WHR for 2 years in a row! We loved it so much we bought one in June in fact!

(Most expensive Disney souvenir I've ever bought! ) I just got back from 4 days there over this past weekend, and it just reminded me how beautiful the resort is, how awesome the clubhouse is, and how nice our home is...it's a vacation destination in and of itself, I could literally go there and spend days in the resort and have a great vacation and never even visit WDW.... sacrilege I know! LOL
It's just so nice to be on a vacation where you're all in your own beds, own baths, the splash pool is just great (our kids love it, but I learned over the weekend, so did all the adults too! LOL) ....
One suggestion for you, if you haven't done it.. if you're going any time up through May, get the pool heat turned on (usually it's optional). We like our pool nice and toasty warm!
We've had several guests who opted not to do this, and several commented later on they wished they had. Many times, the owner's MC will come out and turn it on for you if you decide once you're there you would like it, just so you know (and the resort pool is always heated).
Another GREAT idea from the DIS is to pre-order your groceries for delivery to Windsor Hills when you arrive!
