So the Sheraton, Westin and the condo bldg creat a u-shape cluster of buildings with the Sheraton and condo making the sides of the u and the Westin making the bottom in between.

One other detail I failed to note: I didn't go to the rooftop pool, but heard from another guest that there is a nice hot tub up there.
