Meh. It was alright. Not sure it was really worth it, though. I suppose it's cool to do once. It's not actually a zipline, it's more like a ski lift chair. You ride two at a time strapped into the chair. You ride down and then come back backwards. Not that great during the day - probably better a night when you can see all the lights.
We paid and signed the waiver down at the booth in the casino. Tip: Be sure to ask for the locals discount. There's also a Total Rewards discount. We were then told to take the elevator and look for someone in a white shirt. But the white shirt guy wasn't there, so we went into the store. Then figured out we didn't need to wait in that line and followed another couple to another elevator. There are lockers by that elevator. $6 for a small locker. Don't pay for a locker here. Once you get to the zipline, they'll put all your belongings in a locker for you for free.
After getting off the second elevator, we were inside the Voodoo nightclub and walked out onto the roof. We then walked down the stairs to another booth and were put into a line to board the zipline. The signage was severely lacking and the staff didn't give good directions on where to go.
After stashing the rest of our stuff in the free locker, we were instructed on where to sit and strapped in. Be sure to take off your flip flips or any shoes that could slip off. We then were lifted up and went down the zipline. It wasn't all that fast. The neatest then was flying over the pool area. It was quite quick and short. It's an easy ride and not scary at all.
I was underwhelmed by the experience. The Fremont zipline was definitely much better. Glad we did it, but it wasn't really worth the cost. Again, probably a lot better at night.
