I have been trying to reserve a hotel room in downtown Montreal for a week now. It seems the prices have gone up significantly for May compare to April. My date of travel is May 27-29, which is a long weekend in the US. I am not sure if this drives up the hotel prices or it is just higher in general in May. When is the peak travel time in Montreal? Will the hotel prices be cheaper, in general, if I visit Montreal during the first week of September?
