I'm going to Montreal tomorrow and haven't had much time to plan my weekend. Usually I'm a big planner but I've been burning the midnight oil at work. I have some basic questions but I'd appreciate a response!

-I'm staying at Hotel du Fort on Rue du fort. The hotel has listed a couple stops on the green and orange lines as closest. Can I get the metro from YUL or should I take the 747 Bus? If I take the bus, where should I get off to pick up the green or orange line?
-Are US dollars accepted in Canada or strictly Canadian?

Thanks!
