It doesn't bother me one bit.
If I hadn't read here (long ago) about it bothering people it certainly never would have occurred to me on my own to even think about it.
All we care about is the bottom line -- how much will it cost us to stay at a campground per night? It makes not one whit of difference how that figure is reached--don't care if there's an extra charge for kids or pets or whatever. Just tell us the final amount and we'll decide whether or not it's worth it to us or whether we need to look for another campground.
To me worrying about a pet charge would be like trying to figure out how Walmart (or any other retailer) decides how to price their products. Who cares how it's determined? I just decide if it's worth it to me or not to pay it.
