This will be our third Disney cruise, but the first time utilizing the Dreams transportation to the port ... When we meet for the bus in front of the resort, I know we'll have to have all our luggage with us at that time - BUT How will carry-on bags, totes, boxes or whatever be handled??? Do we have to keep those pieces with us? (On our laps on the way to the port) - OR - can they also be put under the bus with the luggage? THEN - when we get to the terminal - do we wait for our luggage to come off the bus and then deal with a porter individually or will it be handled all together? BUT - If we do have "carry-on" items under the bus - how will we get them?
