We just came back from a 6 night stay at OKW in a 1 bedroom villa (returned home March 5th) ...it's awesome! I was able to get the passholder discount price and it made it worth it...and there was only my mom and I! My reason for the resort was I knew we'd be spending time at the resort. Having a full kitchen and a washer/dryer was super nice! We used the buses because of my mom's
scooter. There are 5 or 6 stops that the buses make, factor in though that if the bus is full it skips the other stops and heads out. That could mean you may not have the bus coming to you right away if you're at a distance building. They'll send another one out, but there's a wait again. I'd request a building near the Hospitality Center (call and make the request!). Not a guarantee, but it worked for us, we were at the 1st pick up stop. The other option is to rent a car for the week and forget the busses!
For the space, you can't beat the OKW 1 Bedroom villa; however, I think you should check out renting DVC points. You may be able to beat that price you received.
