You know, I really don't care whether they have a rule requiring helmets or not. But if they are going to have a rule that is not a "customary" rule (by that I man some rule that you rarely see), then they need to make it very obvious when you are making a reservation. Case in point, made a reservation for a week at a park, get there with 5 kids and 7 bicycles, find out they have a bike helmet rule. Don't have that law here, there own rule. There I sit, 5 kids can't ride their bikes for a week. One trip to walmart and $150 added expense to my vacation for helmets that probably will never be used again. Then to top it all off, the camp host who issued the ultimatum, was gone for the rest of the week and every other kid in the park that check in the day after us was riding their bikes sans helmet. $150 wasted by a POS camp host.
