As a private licensed guide, I organize Romania tours with my own tour operator company - Europe tours including Romania as well. All the tours are customizable and all of them on the roads, as road trip. Why would you make your vacation dependent of the public transport? The number of days and persons depends of your travel plans, so is no need to post one of them here, just contact me and we will establish the itinerary according your time and budget. It doesn`t matter the group size (between 1 and 45 persons). If you are planning a Romania or Europe tour, please contact me, don`t waste your precious time planning something in an unknown country, ask the specialist.
