We are visiting Montreal & Quebec city for the first time during the last week of June 2013. We have 6 days (Thursday to Sunday) for this part of our trip before flying to NY on Monday. We will arrive by plane from Buffalo.
I'm thinking of flying into Montreal first, spend 3 days then catch the bus to Quebec, spend another 3 days, then fly to NY. This means we'll be in Montreal during week days & Quebec during the weekend. Our interests are mainly in the architecture, historical sites, underground city & a trip to the botanical gardens in Montreal.
Am I planning this the right way? Should I spend 4 days in Montreal & 2 days in Quebec? What about the weekend & week days mix? Is it better to be in Quebec on week days to avoid crowds & higher prices?
