Don't have one, but if you're just looking for some fun in a campground, I don't think folks will be too upset. We've been to several places where dads and kids were flying them together. They usually pick an open area in the campground and the kids are playing with them. Dad is usually nearby. They actually draw a lot of attention, and I've noticed folks just shrug their shoulders once they know kids are playing with them. It would be good to check campground rules, if there are any prohibitions first.
I've heard they are banned in National Parks. And if you are not flying them over private property, more than likely you'll not have any problems.
And I think it makes a big difference if you are using one just for the fun of flying it, or if you are wanting to do some serious photography. Just be aware, a lot of folks think they are intrusive into their personal space and react badly sometimes.
