a vacation in france sounds great, i did it a few times and cam totally recomend CHM, la-jenny and Arna.
renting a chalet in those places is a bit expensive but they also have a camping option, if i remember correctly it's around 300-400 euros for a camping pitch for a week, if you go with someone else (or more than one person) it could be cheap enough.
if traveling will be possible next summer i hope i could also go to those resorts with friends, if you are interested you could probably join us.
my first naturist resort experiance was also with them, i met them here in the forum and it turned out to be the best vacation(s) i've been to.
you can feel free to PM me and talk about it.
i think it's also nicer to travel with other people than alone.
