I haven't stayed often, but I found out from a scheduler on the last trip that rooms (studios) that end in 18 have the best view of the theme park from the room. It's straight ahead. Higher floors are better. I can guess that rooms which end in 20 for 1BD and 16 for 2BD have a similar view.
We had a 3 bedroom gv at BLT with MK view. The view was amazing. I would guess that all MK View rooms would offer a decent view. The monorail goes by right in front of you. You can also see the water parade at night with a MK view.
