Ugh, those basketballs are so annoying! I was in KI yesterday, in line for the Scooby Doo ride, and there were two kids in front of me who each had one of those smaller-sized balls. One of the kids bounced his ball too high, and the ball went over the rail and went rolling across the room. I couldn't help but snicker a little when the kid went through all those rails to get his ball back.
I've read some posts complaining about the smoking issues, but when I went, no one was smoking outside the designated areas. I'm going back to KI later today, so hopefully I won't have to experience the smoking problem myself.
