Overnight Bus to Romania

Made our way out along the metro line 3 to the Nepliget bus station.  As we are taking a cheaper bus, we have to wait across the street from the main station.  Time passes and our bus still has not shown.  A large crowd has built up when finally it arrives nearly 30 minutes late.  We join the mass, hand our bags over to be stored underneath for the duration of the eight hour trip and move towards the entrance to board the bus.  The doorman asks for our tickets and passports which we hand over and move towards the door.  Suddenly he barks, "No!"  He is holding my passport and staring at me.  Apparently he is under the impression that Americans (and perhaps South Koreans) can not get visa-free entry into Romania as it is not a member of the Schengen (visa-free) Agreement in Europe.  He is refusing me entrance onto the bus while I am doing my best to convince him that we have checked with the US State Department and indeed we have 90 days visa-free rights to enter the country.  We come to terms that we can board the bus and get to the border, but if we are refused entry at the border (with no city around) we are on our own.  Feeling slightly anxious we board and take our seats when immediately a gal in front of us inquires what the commotion was about.  She says she's from Serbia and that we absolutely would need a visa to enter Serbia, and that she thinks we would need one for Romania too.  I was 100% positive it was visa-free for US (and South Korean) citizens with a valid passport, but now my confidence level is slipping.  Exactly when the gal behind us asks where I am from and says that her American boyfriend was denied entrance just last month trying to get into Romania.  Now my confidence is plummeting and I'm asking people around for a cell phone with internet connection so I can double check.  No luck.  The doors close and off we go.  Not a restful moment for the four hours until we reach the border.  The moment of truth and the immigration officials and a police officer board the bus and start checking ID's.  For everyone it is a quick glance and hand back the ID, done.  Then she reaches us and takes my passport, and then takes Jihye's and says nothing at all.  They finish checking ID's on everyone else in the bus (with one shouting match in the back) and get off the bus with our ID's, still without a word to us.  The gals in front and behind us are silent, and we have no idea and are trying to stay calm.  The bus is just sitting at the crossing and we are the only two that are without our passports.  Fifteen minutes later the bus driver climbs aboard, ambles down the aisle, hands us our passports....and away we go.  All systems go for Romania!!     WHEW!!!
