Walked in on them on my last night in vegas. They are located on the 2 floor in the rio hotel in las vegas. Overall i paid $60 dollars for the zipline and the go pro video package of my ride. They take several photos of you during the ride as well. You can purchase those photos for $25. Overall its a scary wild fun ride that starts of the 51st floor of the hotel. There is a also a rooftop bar you can get drinks and party after.
