We have been camp hosts as volunteers and were required to work 20 hrs each per week for site, utilities including propane, a small freezer, washer & dryer. We however spent a lot of those 20 hours just being available to campers and not really doing any type of labor. Visiting and getting to know people is a pleasant way to put in your time. We would not consider anything that required much more than that, especially where some parks expect "physical" labor for that many hours and you have a set schedule to work. We prefer a more laid back and relaxed atmosphere. We have cleaned restrooms/showers, picked up trash, cleaned the beach, sold wood & ice, checked in campers and collected fees and a multitude of other things voluntarily. We are not opposed to labor, just not labor that makes us want to go back to our old jobs!
