Our DD wants to carry on learning French in the 6th form and is really keen to boost her language skills over the summer. She wants to go to a language school in France for a couple of weeks.
She's not keen to go to one of the teen summer language 'camps' where she would be at the older end of the age range and would be under constant supervision from the staff. So, the only option would seem to be a course at a language school combined with her staying with a host family. She'd have to make her own way to/from the language school each day.
Does this sound like an unreasonable arrangement for an unaccompanied 16-year old? She is normally very responsible but hasn't travelled independently before.
