My wife and I have experience managing several different parks in different parts of the country. We always charged extra for kids over a certain age because of the extra burden they put on the parks infrastructure. More water, more sewer, more litter, more staff supervision of unattended children, and so on and so on...
After 9 11, insurance costs sky rocketed for the travel industry, including RV Parks. How about permits for food service, potable water licensing, Certified Pool Operators. But, in return for those extra fees, the kids had a fun, safe and enjoyable time. They enjoyed a sparkling pool with staff watching them, free mini golf, basket ball and badmitten, and other park sponsored activities. And, they came back, year after year. I'd like to say that if you have to complain about rv costs, then maybe its better that you "go on down the road". Oh, and I forgot to mention, all overnight guests got a major daily newspaper in the morning to go with their coffee and free continental breakfast!
