These hosts reside in campgrounds, providing help to park personnel. Camp near a host and you will be near a person with radio contact to all park personnel. There isn't a safer place to camp. If you want to camp in a park with no camp hosts, camp near a large family. No one will bother you with so many camping neighbors and your children may make some nice friends.
Camping is traditionally a mans sport.
If your children have no father figure - or have a non camping father they will miss out on one of the greatest recreation opportunities in our country. Parents camp differently. Even if your children's father takes your kids camping - it won't be the same trip they take with you. Camping with family or friends can be a lot of fun, but don't replace this with camping time alone with your kids. You may find your children playing with other kids and end up chatting with friends or relatives instead of spending quality time with your own kids.
