As Yensid says you will find a lot of information on the DVC boards as Villas at Wilderness Lodge (VWL) is a DVC resort.
VWL is a relatively small resort so the units there tend to sell out pretty quickly. As with the rest of the resort they have a "woodsy" feel to the resort. You get a master bedroom (king bed), bedroom 2 has ( I think) a queen sized bed and a full sized sleeper sofa, there is a pull out sleeper sofa in the living/dining room. You also have a full kitchen, 2 bathrooms and a laundry (washer/dryer) area.
They are very nice units, similar in size and layout to those at BCV and Boardwalk. You may find that your choice of resort is limited by the availability. Of the DVC resorts generally OKW ( the biggest resort) has the most availability, BW BC and VWL can all show availability at different times (not much rhyme or reason as to which is available at any particular time. Saratoga Springs is the other DVC resort that offers these style units, their availability is usually a little easier to rent for $$$ as parts of the resort are still being completed. With DVC ( Disney's answer to timeshare) the resorts that are available for sale at any particular time, tend to have availability as the units do not have as many owners booking up their times. With the resorts that have sold out, obviously the owners are busy booking their own vacations. OKW being the oldest resort probably has a higher %age of it's owners who will be looking for a different experience (be that non WDW or just trying out different DVC resorts), it also has the most members so you get a lot more availability showing up here. That doesn't mean it's a sub standard resort, it is a beautiful resort and has the largest units of the DVC resorts.
