We were in building 11 in May. We really did not experience the parking problems on our visit, nor did we hear any bus noises. We did not like it because of the woodsy view that we had from our porch (we were in 1111). I felt very claustrophobic on the porch with all the vegetation growing up and around the porch; I prefer the open views of the water ways or golf course, myself. My DS hated it because he saw a snake slither out from under our porch one afternoon; he never stepped foot out on the porch again after that afternoon!
It was not a bad walk to the front, but we still had to walk through the big parking lot to the Hospitality House and pool. I think the walk from the buildings on Pennisular is much more pleasant.
All in all, it was our least favorite buildings in our stays at OKW.
