Bob, we just stayed in bldg. 46 in June and loved it! It is on South Point Road and our villa, #4622, had a wonderful view of the Trumbo Canal. Very quiet.
We also enjoy most of the buildings on Turtle Pond Road (although when we stayed in bldg. 38 last September, our villa was so dark it felt like a cave). Bus noise was also an issue there, although it does not usually bother us. We've never stayed close to the pool area at Turtle Pond, so I can't speak to the noise levels there.
We've never stayed on Miller Road, either, although that it where "my" building is as far as the deed goes - #20.
