Mcds and burger king, I suppose it is possible I have gotten the password before and it’s nationwide. Ditto my gym. I don’t think I have ever asked for password, but the phone can grab it without a problem.
Doesn’t really matter. If he walks to the campground management office and asks for the password, so what.
Well, like I said before, do rural campgrounds have wireless access with Internet available?
Some do, some don’t.
I’ve seen some campgrounds, like KOA on the beach in North Carolina, actually had twisted pair and cable tv hookups.
Then again, I camped in rural Texas, and I couldn’t even get cellular service.
I’m just trying to help the OP plan accordingly.
