DS was going interrailing for 3 weeks at the end of the summer. His friends are based all over the U.K and go from 18 - 20. However there is only 7 actual days they most can do together so not worth it now.
He was thinking of booking a villa/ camping site or something similar so that others could drop in or out over the couple of weeks. They aren’t drinkers, smokers or party kids. They like walking/ hiking and sleeping lots.
Any suggestions for places that might give them opportunities to walk, explore but also be a good base ?
Hes done lots of European cities but maybe somewhere like Berlin or Eastern European. He fancies Montenegro. I’m not organising anything but looking for ideas as the usual party towns/ cities I know aren’t for them
