DS, mid 20s, has a week of work late September. He'd like to go away but doesn't have anyone to go with. He's quirky. Doesn't have a social circle, spends most of his time, when not working, alone.
He's thinking of getting the train to Europe (we are London based). He's not interested in sun but likes fine dining and wine. He's got a week off but would probably be happy with a 5 day trip.
We've scoured the internet but can't find any organised tours (that's what I'd like for him so that he has company and conversation).
Any suggestions gratefully received.
TIA
