Have any of you been to Luxembourg or Switzerland? If so, do you have any campground recommendations? Or good parts of either country to visit?
Ideally what we'd like to do is to go to both, find a nice area in each to make our "home base" for several days, and then do a bit of hub-and-spoke touring from those bases.
I have located one campground in Luxembourg, but a difficulty we're encountering is that many campgrounds here in Europe do not allow tents, and I can't tell if this one I've located does or does not. Another difficulty we're encountering is that some campgrounds seem to be members only ... no tourists allowed. It makes finding decent campgrounds a bit more challenging.
