We had a washer and dryer in our condo at Wyndham Palms Resort and Country Club. It was a brand new unit (1500 square feet). Two nice sized bedrooms, big screen tv, screened-in balcony, full kitchen, dining room - quite nice and about a five minute drive from WDW.
We stayed there two years ago. While I prefer to stay on-site, this was a good choice if you need more room at a reasonable price.
