What sort of "holiday" will you be looking for? Is it beaches and hotels, touring, back-pack, etc.
Don't be put off EE by the stories of pick-pockets and crime, I have been visiting EE for over a year now, lived in Chisinau (Moldova) for 2 months last year, and I found the people exceptionally friendly. Romania in the countryside in summer is like a trip back in time. The Carpathian Mountains are spectacular, I've driven across them twice. It is more difficult to find English speakers outside of tourist regions, and even in main transport stations you may find that nobody will speak English. Can't tell you about the beaches because I don't do beach holidays. Transport is fast and cheap though, buses, coaches and maxi taxis are the norm, trains are a little more expensive and long distance journeys may only have one train a day.
Please ask if you want more info.
