I've got a bunch of vacation time to play with and thought a quick trip to see some beauties in eastern europe would be a great way to spend some of it. Problem is, I don't really know where to start. Having never been to either city I'm not really sure if the areas are safe and thought a tour would be the best way to go about it...but I'm open to suggestion. Anyone have any input about either city, advice on how to begin planning, agencies or clubs, etc? Thanks in advance!
