Eastern Europe city help

[Elliottz28]

Hi, I'm really interested in Eastern Europe and i had always wanted to travel to the czeck republic and poland russia ukraine etc, but reading posts I'm also interested in bulgaria and romania and other more of the southern eastern europe countries. So i was wondering if you have a good list/itenerary of cities to travel too, preferably with night life and fun stuff like that, i'll be 17 during my trip in about a year and im not sure about the drinking laws. So it would be great if anyone could help me out with this, i think my trip will be from a 1 1/2 to 2 1/2 months hopefully. thanks
