There are some threads on Romania; you might wanna try a search.
I hate to give you the boiler plate answer, but please tell us more about yourself and the purpose of your trip:
- What are your interests? What kind of experience are you looking for? (Quiet&relaxing / adventurous / fun&exciting / luxurious / ...)
- Are you traveling alone/with family/with friends?
- Some hint towards your age range usually helps.
