thanks everybody.
I guess I have to do some more research.. the bus station Im talking about is in Sapporo, Im pretty sure its not sapporo staion tho. there's only one train going to it, and theres loads of buses there, many taking the locals to work.
but there are also some small bus companies that do trips up to the resorts.
as for the tower hotel, thanks for that tip, but were already set up with flight and hotel. pretty cheap.
my friend who lived up there last year (cant contact him now said this was THE station with all the buses. cheap rates c
