We have a once-in-a-lifetime opportunity to take 4 weeks away over the summer holidays, but we are having trouble deciding where to go! Ideally not away for the full period, maybe a couple of weeks doing something a little adventurous and around 10 days in a villa / similar. I don't like camping. Myself, DH, DC 13 and 15. Wondered about Interrailing for a week or so, but even then there is too much choice! Where would you go?
