We love DVC!! We would usually go every other year and stay at the moderates, then we bought DVC. We are a family of five(DH, me, DS13, DS10 and DD5) and the regular rooms were getting too small. With DVC you have plenty of separate rooms, washer/dryer in the room(or available free), kitchen area or wet bar, etc. We have figured out what we would have paid for the accomodations that we have stayed at with our DVC and it has paid for itself in 4 years! And, we still have it available! We love the large villas and all of the activities at the DVC resorts. We have stayed at Hilton Head Island and Mackinac Island, MI using points as well.
Can't say enough good things about DVC. It's Great!!
