Forget the above choices (except you are planning to work) - if you want to have a nice little vacation go to NICE. I can set you up with a real nice youth hostel (by far better than anyo of these hotels) AND a few sexy lovely gentlemen ! I have been there with my lover recently and WOW!
If you want to work though, i recommend San Francisco. London is stressful, and LA too many women and too "wide" for a european. San Francisco is lovely. MWah! btw, i tried to find you for exchanging banners, you don`t really have a homepage, do you? Like your blog.
Oh and btw: staying at other people`s places when you cannot afford hotels: Miami i have friends, contact me, i might be able to help, no promise though. And very helpful is something like
www.couchsurfing.org .Not only does it offer great opportunities, but i also found two of my current longtime lovers on there. Yummy. ;-), and hey Julian Assange was on there too :-) So it can only get better, right??
