When we go to Disney our travel costs are high, so we go less often for longer trips. We have stayed at a free timeshare (using Marriott points) for the first part of our stay, then at a DVC. We find that we really enjoy the Disney portion of our trip best, but splitting the stay is the best way for our family to make ends meet. We still enjoy the 1st part of each trip, but what we've realized about other resorts/hotels is that often they're very spread out, and having to use the car constantly takes away from that vacation-time-in-a-bubble feeling we get while staying at Disney.
I highly recommend looking at renting DVC points to stay at Wilderness Lodge Villas, rather than a room at WL. You will pay much less money for a nicer room. Check out the Rent/Trade boards to get an idea. For example, often you can rent $10/point. A studio at the Villas at WL in January at $10/point would cost $600 for Sun-Thurs. There is no tax. A regular hotel room at WL during the same period will cost you $1125, plus tax. So add at least another $150, and I'm not sure if they have other fees tacked on. The DVC studios have a small refrigerator and microwave, which we love. Even if you eat all of your meals out it's so handy for snacks or being able to take back leftovers. We generally eat at least breakfast in our room. We have 4 kids so we need to get a 2BR, which has a full kitchen. Much more economical for us, since we would need 2 hotel rooms otherwise. We stayed at the villas at WL a few years ago and loved loved loved it.
