VRBO is the best site. Search by # of bedrooms and select homes that say 5 min to Disney if you want to be closer (never takes 5 min but it's close). Best communities are windorhills/palms, Formosa gardens, Indian ridge, rolling hills, emerald isle, Indian ridge oaks(older).
You send eMails direct to owner so you can try to negotiate a price that fits your budget. usually sites have lots of pics. Many post the address so you can googleearth the home.
We've rented everything from 4 bedrooms to 7 bedrooms. Loved them all.
Have fun house hunting.
