help finding someone?

[Jack]

hi, was wandering if any experienced internet searchers could help me.
I'm trying to find a girl with the first name Alexandra.
I think she is from france but possibly german/spanish/greek.
I know that right now she is in puerto del carmen, lanzarote, spain. The hotel is called THB flora.
she is around the age of 16/17.

If anybody could give me some tips on what search engines to use or facebook/twitter advanced search methods I would appreciate it. I want to find her profile to contact her.
please people, I think I might be in love with this girl and as soon as she leaves to go back home which could be tommorrow, I won't have anything to find her. Her first name and current location is the only unique information I have to seperate her from thousands when she leaves this place. I just need to know hot to put that location and name together to find a profile or something. Or I was thinking searching tweet phrases with keywords like lanzarote, holiday alexandra whatever. Need some help here guys.
