Borrowing the map from above, I added yellow
Xs in all of the areas we've stayed at Pop.
We've only booked standard rooms and the only requests we've ever made were the last two trips when we requested 50s and, this last trip, ground floor.
That said, the rooms I've liked the most were in the 60s. Both of those trips pre-date the Skyliner, but we generally just found them very convenient.
We like 50s because it seems a little quieter and by skirting along the buildings or the lake, the walks anywhere aren't too far.
Both times we were in the 80s also pre-date the Skyliner, so it wasn't too bad over there because it was a quick walk to the buses.
Now - as far as specifics in the rooms? The quietest rooms we've had have been on the 3rd floor. But the elevators are slow so be prepared for stairs at the end of a long day in the parks.
This last trip, we were in 50s building 2, near the end of the wing, and had hardly any water pressure in our shower and it was hit or miss if we'd get decent hot water. I didn't mind the location, but it was my least favorite room for that reason.
