We're DVC and managed a 2-bedroom at the 7-month mark for the last week of May (starting the day after Memorial Day). There are several DVC rental outlets. There's also a DVC forum on here where you can probably get some answers too. Your best bet is to link up with an owner at GCV either directly or through a rental agency.
Some perks of the room are proximity to the parks, laundry (either in suite or close by if you're in a studio), and kitchen (unless you're in a studio, then you'll have a kitchenette).
