BUT, she also wanders into their campsites to "socialize" when they are here.
I don't think you mentioned that before, I can see how that would be awkward. But again, if anyone says anything to you about it I would just apologize for the awkwardness and tell them she'll be gone before long. Don't say anything you don't want getting back to her though. For example, you might be inclined to tell them to tell her to leave them to their privacy if she keeps wandering into their sites, but surely they're smart enough to know they can do that already and if you tell them and it gets back to W it won't go over well.
