I stayed in Rock In building four for one night in August. We did not have preferred. I wanted to be near a parking lot. It was very quiet. It was also a tremendously long walk back to the food court.
I would request top floor and end of hallway for quiet. So, if you look at the buildings like a T, we request rooms on the vertical part of the T that let out at the parking lot and top floor.
We had a preferred family suite in Calypso, so maybe not helpful for the selection you’re making.
