I am looking at traveling to Eastern Europe at the end of this summer or in the fall, and I just had a few questions about renting a car, and driving it between different countries in Eastern Europe. Right now, my trip plans are still up in the air, but I sort of have an idea of the places I might want to go. Right now, I would like to travel to some of the following places: Hungary, Romania, Bulgaria, Serbia, Bosnia, Croatia, and/or Slovakia. So, my question is, which of these places would have the fewest restrictions on rental car travel? I know that a lot of rental car agencies do not allow cars to be taken into former Soviet Union countries. So, is there a place, maybe even not one that I have listed, in Eastern Europe that would allow me to go to most, if not all of these places? I know that is an extremely broad question, as there is tons of rental car agencies, but if anyone has any information or an idea, please, let me know. Thanks a bunch in Advance!!
