Heading to Moscow? Not sure what to do; but sure you want to fuck as many gorgeous dyevs as possible. Check out Moscow Rick.
http://www.moscowrick.com/ He is an American ex-pat who primarily advertises apartments to rent in Moscow. I always stay in one of his units. Good apartments at a fair price. But this guy can set you up with amazing ladies. Party because he is a principal in the Hungry Duck (a club that is not to be missed
http://hungryduck.com/). Partly because he understands both Americans and Russians alike. And he is one of the few people in Russia who can be trusted. Check him out. You will definitely want to stay in an apartment and not a hotel. Most hotels will make you use their girls and you can not bring any other lady up to your room. Apartments are great for overnights.
Just a tip from Uncle Cheb!
