On my float the lady was really worried because she had so many minors on the float and minors cannot be on the top portion. So I believe there may have been more minors, but it had nothing to do with no people, because these were all people that either knew they were riding because they know someone who works at Universal that got them bands in advance or took advantage of the Amex deal that I took advantage of.
I don't remember passing the river boat when we were walking up to our float (we were the second float), but I think we started walking past them in the middle, so not sure.
Hmmm... didn't know about anyone from Harry Potter being there, but then again I doubt they would tell us anything unless you were on the float with them - lol
It was fun and I was trying to chuck them pretty far, the guy next to me kept laughing because I was chucking them so fast and far. But that whole underhand toss and the one bead at a time that they preach to you really stops people from chucking them far out there. I kinda listened and kinda not, but they don't yell at you when you don't listen to the rule either. In fact the lady kept saying how good of a job I was doing. lol
