camping with extra adult

[DNS]

In resort rooms there is an extra charge for more than 3 adults. Does anyone know if this the case with the campgrounds? My in-laws are going down and wanting to take my mother-in-law. They have a motor home, but wanted to know if it will cost extra for her. They are trying to figure as close as they can to what they need to budget.
Thanks in advance!

Not 100% on this, but think that there is. It is like 2 bucks an adult, or something like that.

That's not bad at all. Thanks
(I meant to say a charge for over 2 adults.)
