We actually liked OKW without a car. Our villa was very close to the bus stop so it was really easy to hop on the bus without a lot of walking to get there. Plus if we forgot something in our villa, we could easily run back to get it. Riding around the resort before leaving for the park is a bit annoying, but definitely not worse than say walking down the long BWV hallways, down the sidewalk to the bus, and then to the S/D, BCV before hitting the parks. I'm sure AKV would be a similar long walk just to get to the bus stop, but without the stops at the other resorts.
Well if anyone that currently has a THV booked for 12/6 - 12/11 wants to dump that ressie due to not having a car.... let me know!! We have fingers and toes crossed that we can get a THV for that week.
