It is a long journey, why not flight? Nowhere is like your home, I think this is a general feeling. Even, some people can't shit somewhere else except their house :)
I don't formal social business organizations. Years ago, workers from my deparment went to a hotel for few days. Most of them went too far with drinking, and it never happened again :)
There is a plane trip in the middle. Either side of the airports though, there are trains or buses.
Finns are well-known for their drinking culture. :)
