Picking up girls in Foreign Countries

So i plan on going on vacation soon and i was wondering how to go about picking up a girl in a foreign country and know little to no understandning of there language. Any creative or interesting ideas on how i should go about getting them home for the night

Learn the very basics of the language. Learn how to say hi. Or good morning, or whatever is appropriate. Learn how to say I wish I could speak your language better, but thank you for your patience with me. Be sincere and don't smile too much.

Trust me. its the easiest gaming you will do. When I was in sweden I asked a girl for a lighter, she got so excited that I spoke english she went inside and came out with 4 of her friends to introduce me.
Unfortunately this is still one of my biggest regrets to this day, Was having a girlfriend while I was there.
You can just ask girls anything, How do I say thank you in their language, start joking about how good fluent you are in their language.
I dont think picking up in another country should even count, its more of a fools mate thing.

I'm going to London on Monday for a week. I'll be staying in someone's house with two classmates and the residents of that house. My English is at CAE/CPE (C1/C2) level so that's almost native. Do you think, knowing that, I could still make use of the "foreigner factor"? I'm better at sounding American than British. That might be helpful.
