DD (20) has decided she wants to spend some time in Spain next year, mainly to help her improve her language skills. She's around C1 level (though rusty!) on the European framework currently, if it makes much difference.
Trouble is... what does she do when she's there? She's not keen on doing any of those programmes where you pay hundreds of pounds to be given an unpaid job/internship/whatever. Language lessons seemed like a good idea for her, but a month of intensive courses would be going on €1000, excluding any general living costs. Not sure if she would be able to work part time alongside lessons, or how/where she'd find a job to at least partly subsidise costs. Ultimately she wants something that forces her to interact in Spanish, so no club rep jobs in Ibiza or anything! 
Wondering if anyone knows someone who has done a similar thing and can give ideas? DD would be thinking of going over summer, but can't stay much longer than 4-5 weeks due to other commitments.
Thanks in advance
