We've stayed 3 times in a 1 BR villa -lake view and got our request granted twice.
We asked for north facing, even numbered higher floor villa. We got a perfect view of the monorail, castle and nightly fireworks, so amazing when the kids were younger and we couldn't do late nights! These rooms are on the outer circle (BLT is U-shaped), so you don't want to be facing inside the U, which is definitely lake view only.
