We stayed with
www.romancingthemouse.com and it was great!
2 years ago we stayed in the 5 bedroom house and this coming April we are staying in the 6 bedroom one.
You get their 30% discount rate if you are referred. Feel free to PM me if you're interested and I can give you my email address to use as the referral (I get an extra 5% off our next stay as well).
A couple things to note with RomancingTheMouse...
1) their prices include everything - taxes, pool heat, everything.
2) Excellent customer service - they greet you at the house (you don't have to go somewhere to meet them) with fresh from the oven cookies as well as juice and muffins. They give you a tour of the home and show you how to use the tv equipment. They will give you Disney tips (not like DIS'ers need them

). They'll let you know what groceries store to go to, etc. They will even give you their cell phone # to contact them if you need anything!
3) we signed up for their free romance package and so we also got chocolate covered strawberries delivered near the end of our stay.
4) The owners live in the Windsor Hills community, so they are right nearby if you need anything.
5) They provide the essentials like toilet paper, salt & pepper, etc so you're not having to buy
everything. All those little details add up to a wonderful experience!
I couldn't recommend them more highly!
