The Club Saint Louis has the slings above the bed in the VIP suites. I never get a VIP room because I don't see anybody use that setup, regardless of height/weight. I do really like the public sling room at CSL, it is not adjustable.
I had a bf that could rig up the sling over the bed in the RV(limited space), but the ceiling connections were heavy duty springs, so the top held on to the bottom and took us for a ride. Few people could cum that ways, butt there were few barebackers then.
It seems like Steamworks Chicago has sling rooms too, with awkward setup= too close to the floor or the bed. I have had fun in the public sling. I really like Chi Steam's fuckbenches best.
