I'd like to add one....
If your child is visibly sick, LEAVE the PARK IMMEDIATELY.

We were waiting to board the Safari in AK when my husband looked at the next line over and saw a boy of about 3 or 4 throw up. He was with his parents or grandparents and they did not see it happen, so my DH leaned over and said "Excuse me, he just threw up." The adults looked at the puke on the ground and then looked at the kid's face, shrugged and said "He looks fine." They then proceeded to get on the ride with us

Every time we went over a bump (and there are a LOT on that ride) I worried that kid was going to lose his lunch all over me. Fortunately, he managed to wait until right when they got off the ride, then puked again.
On the other hand, I think sometimes people make too much out of it. We were waiting to go back to our hotel when a little girl got sick right as she was getting on the bus. Well, you would think she had projectile vomited all over people with the comments they were making. Give me a break, Sure, it is not pleasant to smell, but there is no reason to make pointed comments - after all there is nothing that can be undone at that point. I am sure she felt bad enough already without the nasty looks, and her dad WAS already trying to get her back to the hotel. They waited for the next bus while the dad cleaned her up, and the people who were getting on that bus treated them like they had the plague!
