Nobel, if you're headed over to Europe I would really recommend that you head to Amsterdam and stop in at Club Elegance for a GFE. For about the price of a single hour with one provider, you can have two over there. Furthermore, I find that the best way to ensure a good experience is to find a girl you like, chat her up and buy her a few drinks, and then for the second woman ask, "so, who do you like?" It's pretty much guaranteed that you'll have a fantastic time. The only problem is that you'll probably want to spring for a second hour (not such a bad thing, from my point of view).
