Just out of curiousity what would happen if you didn't make one? I'm sure it happens all the time, and obviously you should call up and cancel if you know you aren't going to make it in. But lets say we get into the park and go to our eating spot and a child has a meltdown and we leave? (This is just out of curiousity, I would def call and cancel but i'm just wondering what would happen outside of you just not showing up)
