The deluxe villa resorts are also known as the Disney Vacation Club resorts. DVC is Disney's timeshare system.
The resorts offer a home-away-from-home kind of vacation, with studios and 1, 2 or 3 bedroom villas. Studios generally have a queen bed and a sofa bed; some also have an additional pull-down bed. The OKW studios are the only ones with two queen beds. The 1, 2 and 3 bedroom villas have a full kitchen, washer/dryer and most also have a jetted tub. Some have multiple bathrooms (usually as many bathrooms as there are bedrooms, with some exceptions).
You can book deluxe villas in two ways: by renting a reservation from a member (commonly known as "renting points"), or by booking directly with Disney. If you book with Disney, you'll get full daily housekeeping. If you book with a member, you'll get trash & towel service daily, and a full cleaning less often.
