what is the room with the balcony that overlooks the lake with the huge tub?
I believe you are referring to the Whirlpool Suite. That has a whirlpool tub, the picture window looks out over the lake, however, there is no balcony.
Sorry, my room was in front facing the parking lot. Additionally, I was there in the middle of February so I have no idea what the grounds look like. I can tell you that the room was clean and neat.
