The buses at BCV and BWV aren't that bad, because you don't need to use them as often. The wait is often long, and they are shared with other resorts, but you never need to get on one to go to Epcot or MGM. You can also walk to Epcot and take the monorail to MK. I would say that is the best location to avoid using the bus. I have stayed at OKW too, and the buses come pretty quick, but it seems like more of a pain.
