Why not try the best of both? Rent points from a Disney Vacation Club member and stay at the Boardwalk Villas, Beach Club Villas or Wilderness Lodge Villas. There's also Old Key West, but unlike the other three, it's not attached to a full-service Disney deluxe hotel. We've been DVC members for just over a year and the accomodations are fantastic! If you get a one-bedroom or larger you have a full kitchen and washer/dryer in the unit, a king-size bed and HUGE jacuzzi tub, and two full rooms to stretch out in. Now, we don't cook a ton on vacation but it's sure nice to have a fridge to keep drinks in and the ability to eat a quick breakfast or late-night snack in the room. Also, we don't have to pack as much for longer trips since we can do laundry right there if we want. If you're in a studio you'll have a mini-kitchen (coffee maker, toaster, microwave, mini fridge) in your unit and access to free washers and dryers in a laundry room.
There's a DVC rent/trade board here on the DIS - with an FAQ post at the top you should read first. Renting from a member will save you about half off what Disney charges for the rooms.
