I have made it out to Spain with my two teenagers (single parent) for a week of relaxation and sunshine.
Teen 1 (16) is having a great time; tennis, swimming, jet ski etc and coming out for meals and drinks in the evening.
Teen 2 (14) has not left the villa in 3 days....stays in the bedroom on devices and won't come out for meals/drinks out.
Should I ask that teen 2 comes out or leave them to it and not invite them on holiday again. They were both asked if they wanted to come and both said yes!
