I have only brought Canadian money to Negril for the last several years. As far as paying for a room in Canadian that only happens when you buy a vacation package from a Canadian tour company. Luckily there are several packages available to Negril from Canada. I used to always book a flight and find my own transfers and rooms, but not now with the weak Canadian dollar,I have even switched back to the AI option as the exchange rate is a deal breaker.
