It is all very personal as to what any individual is going to consider a great location and great view or whatever. We have stayed in all parts of OKW with the exception of Old Turtle Pond, and I have yet to be dissapointed in any of the locations. Each has some pros and cons, like any other hotel or timeshare unit.
My personal preferences for BEST buildings I've stayed in at OKW are building 55, 56, 52, 45, 46, 21 and 13. I have stayed in many more, and the two I liked least were 64 (no parking lot) and 29, but that was because we were on the 1st floor under a GV, and we had a bunch of very noisey people above us. Best views, in my opinion, are 46, 55, and 21. Bear in mind that I have not stayed at Turtle Pond, so have no real experience with those views.
