Don't give up! What is your budget per night and when are you going? Check out the Bonnet Creek Thread....we are here now in a 3 bedroom for $125 a night including all taxes. Another person is renting in Sept. and was quoted $69 a night for a 1 bedroom and $89 for a 2 bedroom. There are incredible deals to be found around Disney in some really nice resorts. These boards are a tremendous resource and I know you will get a lot of helpful suggestions.
Another place that we have stayed at is Regal Palms...little further away but can also rent three or four bedroom villas for like $500 a week. Regal Oaks is also pretty new and a great deal.
Also...consider a house or townhouse rental through VRBO or homeaway.com. SkyAuction is another option, but you have to watch the fees and read the fine print. We have snagged deals through them for $249 a week in two bedroom villas!
If that is more than you were thinking, that doesn't take into account that it has a full kitchen so you could save a ton of money by eating in some meals. We have been eating breakfast here and even grilled hamburgers for lunch one day.
We have three teens and know how expensive Disney is. But we have learned to search for the best deal possible and have stayed at some great places over the years. Hopefully, you will be able to find one as well!
Good luck to you!!
