Ruska also isn't a place where I would like to be in the middle of the night, lol :D If I'd have to choose I would prefer to be near the train central station at night ;)
haha you are right on that one, It can also get pretty spooky around there late at night :)
don't forget there is phone ticket reservation for buses! If you didn't reserve your seat then you can enter the bus if there are free seats.
Contbus actually cancelled this reservation service because many people just called to reserve a place and sometimes didn't show up. Now you must buy the ticket on advance from contbus.pl however I have never done this.
I have caught the same bus many times myself to Pulawy, which if you don't know is on the way to Lublin.
The ones going to Lublin don't go through Pulawy, however once there was an accident and they closed the road, so the only way to get to Lublin was through Pulawy :)
