I was in the Nationality Rooms tour guide program while at University of Pittsburgh, and one year our annual trip was to Toronto. We went over MLK weekend (if you think Pittsburgh gets cold...), so, granted, it wasn't the best time to go, but it wasn't a horribly long drive and things were cheaper there (this was 2008, so I don't know whether that's changed). But we went to Casa Loma, Niagara, and a lot of great restaurants.
