Salut,
So I've just booked a trip to Quebec City for the last couple of days of Carnaval.

Anything I should know about, book in advance, etc.? I've obviously looked at the website, and there seems to be a Saturday night parade and a Sunday brunch going on, plus something called the Derby St-Hubert. My basic plan (such as it is) is to walk around and check out the free stuff, but I'd love to hear from locals whether I'm leaving anything out.
Also, will the tourists pretty much invade the entire city, or will it be limited mostly to the usual places? Basically, can I grab a quiet drink or three at Sacrilege without facing mobs of people visiting from Gaspésie?
Merci et bonne année!
