Unaccompanied teen holidays

[Verbena37]

Hi,
Has anybody had a teen (under 18) go on a holiday abroad unaccompanied?

DD is keen to find something volunteering with animals etc or anything really that allows her to go away this coming summer (without us) but abroad.

I can’t see anything that doesn’t £1k+ which is totally out of the question but wondering if anyone knows of any universities perhaps that do student summer programmes? Somewhere like Italy/Spain/ Finland etc?

Dd will be 17.5yrs.

My ds was 17 and he and a friend went travelling around Italy last Summer and had a great. Nice mix of culture, beach and relaxing. Gorgeous hostels and really cheap in places like the Almalfi Coast and Rome.

Word of warning. If you are under 18 and stay in a hostel in Italy you must have a parental letter giving permission. I had a panicked dc on the phone at 10 pm on the first night asking me to fill in the form.
