Just to correct a previous post--it's only 50 cents to transfer from the Go Bus to the Oshawa Transit. The bus you want to take is the 1 simcoe northbound towards durham college. You have to simply show your go ticket and it's 50 cents. Since I'm horrible with directions you might want to ask someone where to catch the 1 simcoe, but simcoe street is right at the bus station so you shouldn't have any problems. Also, I believe during the day it runs every 15 minutes.
Also, the 1 simcoe does its LAST trip out of the college at 11:55PM. From 7:55 onwards it's only hourly, so keep that in mind. If the dance hasn't finished by 11:30, I will be making an announcement reminding people that the last bus is 11:55
 Also note that the 1 simcoe is the ONLY bus you can take from the college to get you back to the go station without doing eleventy billion transfers.
