estimated costs: if you choose to go by 2 persons per room, the price is around $120 for one plus tax (4 persons per room is much cheaper).
the price includes accommondation for sure, and several meals, not all of them though. you may be taken to a french restraunt in quebec city and you will pay for that. and the tour guide will collect tips from you at the last day, which i remember is $15 for one.
the tour will take 3 days and there are 2-3 groups leaving every week.
