I would highly recommend a day trip to Quebec City. It is cute, although a little touristy, but still worth seeing the architecture and views.

In Montreal, I would recommend the Atwater Market early in your trip or at the end so you can pick up fruits and cheeses.

We also really enjoyed dining at the Beaver Club in the Fairmont Queen Elizabeth. Definitely a pleasurable and classy dining experience.

Some the streets can be sketchy in the morning, before 9, like Rue St. Catherine in some places. Be mindful.

Olympic Park and BioDome are a waste of time and money. Jardin Botanique was good and I would definitely check it out. Did I say BioDome is a huge waste of money... oh yes I did say BioDome is a huge waste of money.

Have fun. Remember the exchange rate sucks from the US and you can NO longer get a refund on TAXES for goods purchased for personal use and hotel accomandations. And the sales tax rate in Quebec is horrible!
