I was a chap'rone for a group of 75 HS kids yesterday. We were together to hand out the tickets and next saw the group at 7pm to head for the bus.
These were kids ranging from 15 up .... they had the run of the park. Our rules were goups of 3 minimum, don't leave the property. Most had cell phones...each group carried their chap's #.
If there was a problem they were to go to anyone with a 'name tag' then ideally head to the main first aid station in either IOA or Uni. I didn't see ONE of the kids all day!
I've done this for several years. They are old enuf....we've never had a problem more serious than a kid needing a bandade from a trip and fall or a blister
Yesterday gave dd $40 for food, she came back with $15. Bottled water is running $2.75 now and yesterday was HOT.....figure that in, altho you can get ice water free at any concession stand too
