We actually got a phone call to our room phone inviting us to participate, but we couldn't the first day, and then the second day it rained.
Does anyone know if there are age restrictions? Next trip I will have teenagers with me. I wasn't sure if they could do it or not.
Also, if you do get picked, please be careful with the throwing. Some of the people throwing the beads were really chunking them to the point it hurt when they hit you. I got hit in the face and head a few times pretty hard. I felt like the dummy for a target practice session. I've never experienced that before at Universal or in New Orleans, so I'm thinking it was just overzealous park guests who were really excited about getting to throw those beads!
