Good luck to the poor park employees who are going to have to enforce this.

I worked at an amusement park when I was in high school that decided to ban smoking in the park one season and move the designated smoking area outside to the parking lot. I took so much abuse that summer trying to enforce the rules, dealing with upset guests coming in and out of the gates to have a smoke, forgetting items in their lockers and having to walk back, etc. Far more abuse than I took from guests in previous seasons over people smoking in the isolated smoking areas that already existed.
