I have another travel question. I found a Youth Balkans Pass for train travel that covers the following countries that I will be traveling in: Greece, Bulgaria, Romania $112 dollars for 5 days in 1 month which pays for itself with 3 of the trips I wish to make within these countries. My question is --- Will it be much cheaper to travel by bus in these countries? And if so, what is the quality of the travel? I can't seem to find any websites that give prices for bus travel. Does anyone know of any websites in English that can help me out?

Any help on these questions will be appreciated. Tiffany
