once you make your way to playa, either by taxi, car, or ADO bus, you can easily walk with your luggage don to the ferry dock. there are porters around if you need help but it is a pretty short walk.not a big deal. after you buy your tickets you wait in the holding area. when it is time to board you make your way down to the pier with your luggage. at the boat they will tag your bags that have to be stowed. you can carry on small items. once in coz you claim your luggage on the pier after disembarking. the bagge guys will match your tags with each bag to make sure no one takes the wrong ones. then you walk with your luggage toward the street and their are taxis waiting there. piece of cake.
