How do you feel about people walking through your campsite?

It is obviously generally impolite to cross someone else's site, but there are some exceptions. We often stay in waterfront sites where the waterfront itself - whether stated in campground rules, or obvious by use - is common area for all to enjoy. Often, there are spaces left for walkways between certain sites for access to the waterfront, but sometimes not. At those parks, there is not way to get there except through someone's site. In those cases you just have to be as polite and non-disruptive as you can ..... and sometimes kids will be pretty excited when heading to the waterfront!
