The Mountain tower shares elevators with the other end of the Soco.
It’s closest to the parking garage, checkin desk, lobby cafe, and Selu Garden restaurant. It shares elevators with one side of the Soco. The Creek tower is the newest (but is showing some wear now imo). There are two indoor skywalks that cross the creek, connecting the hotel to the casino.
Because the hotel towers are on one side of the creek and the casino is on the other, and because both sets of elevator banks for the hotel are on the complete opposite end from the casino, you pretty much have a 150 yard + walk.
