I'm 16 and the second I heard about skyjump I immediately called to reserve. My parents signed the waiver and I was good to go.
The staff in the office on the ground were very distracted by each other and did not look like they wanted to work there AT ALL. I got suited up and taken up to the 108th floor where the happier staff are. Two people on that floor did multiple checks and I was out on the ledge ready to jump.
I got the video+photo package - the video is shot with a gopro hero 3+ so it's perfect but the photos are practically useless.
4 stars only because of the staff and the 'photos' you pay for (they're really just you BEFORE the jump). I enjoyed it and would recommend that you do it when in Vegas.
I didn't get any sort of adrenaline rush but it was still a lot of fun. I won't remember what it felt like but i'll remember that I jumped 855 ft at 42 mph.
