DD will soon be 18, DS has just turned 21. I'd like to gift them a short break together early in Sept. Destination is not as important as having the correct setup. By that I mean that it would be nice if they were part of an organised group where they get together to visit places and do activities but there's also scope for doing things independently. I've come across some 18-30 groups but I feel my only just 18 DD will feel really self conscious if the group is mostly 25+. Any thoughts where I could start looking?
