We were in southern Bavaria in May this year. Lovely but a bit wet!! Not being great linguists we liked the way English was very widely spoken (much more than France). also had problems with using Credit Cards. Fuel and large tourist attractions okay but restaurants and supermarkets varied but mostly didn't accept them.
Don't forget to leave a review of the French and other European campsites you have visited!
Thinking of following the Romantiches Strasse next year.
A few nights at the top, a few in the middle and some more at the end.
Anyone done it and recommend ACSI campsites?
