The Vacation Club board will give you more opinions.
If you have a car, all buildings are pretty much great. Some prefer some and some others, there really aren't any bad buildings.
OKW is set up best to have a car. I like to be in the Turtle pond area, but I don't even request a location and I have been staying at OKW annually since '93. I have stayed in a different building every single time. Other than a couple real minor things, I have found no downsides to any location.....but I always have a car.
