Another important consideration that you need to take into account is the length of the journey that you will be making. There are boats available that can easily carry up to nine people but if you only plan to spend a couple of days in Canada then you would need to take into account the cabin capacity. The larger your group, the more expensive it would be to rent a ship. It would also be easier to travel with others, as it would be easier for them to handle their luggage and board the ship.
