This is a must-do if you are in Downtown Vegas. I also recommend doing it at night when the street is lit up! We made a reservation (highly recommended) and then did a little drinking and gambling until our time. Now, a reservation doesn't guarantee you go at that specific time, just that you do not have to wait in the line once you get up to the zip line area. Once we arrived at that area, we waited about 10 minutes to harness up and then about 5 minutes to actually go. However, if we didn't make a reservation we would have had to wait in a line where it was first come, first serve between reservations.
Anyway, the guys who put on my gear were very nice and polite. At no point did I feel uncomfortable. I felt the harness was very secure and felt as if they did a good job of securing me in. Once we were geared up and ready to go, the guys did a final safety check and we were off!
Now, the ride is short and the takes less than a minute, but it is totally worth it! It's a unique feeling to be zip lining above a crowd of people! Once we were done, the guys unhooked us and we were on our way!
We decided to purchase some pictures to commemorate the night with because it is definitely an experience!
