15 yr old ds wants his girlfriend to come on family holiday

[meercatmum]

15 yr old ds has asked if his girlfriend can come on family 2 week holiday villa in Spain. He says she has never been abroad and that cost of flights will be covered by her and his savings from a part time job. There isza spare room available and she is nice enough. However I feel this is v young and am uncertain how this will change family dynamics. Dd is 13 yes old and is going to be assessed for aspergers so can get v easily upset and anxious. She has quite serious self esteem problems and gets very angry and spends approximate 1.5 hours putting on foundation makeup. She like ds girlfriend but feel concerned about it all ... Son argues that dd would behave better with another teenage girl there ...hmmmm possibly.
Ds will get really upset if we say no because as far as he is concerned there is no money implication and we have the space. Would be interested to hear others views on this as it is hard enough on a day to day basis with the 4 of us and I do realise ds often has a tough deal with all energies spent on ds and her issues at home and school!

I wouldn't mind if it was a friend but I wouldn't want the girlfriend to be there.
