We're going to be in Montreal in 2 weeks, staying in Laval, and will have a car. On a Saturday afternoon we were planning to visit the Old Montreal area. I was figuring out the cost of transportation, and metro is $5.50 for a roundtrip, so it will be $22 for our family. I found there's a couple of parking lots in the area that charge $7-10 max all day on Saturdays. Money-wise sounds like a better option. Is it a good idea though?
