We are going on our first Disney Cruise out of Port Canaveral in March. We will be staying at the Hyatt Regency Orlando Airport the night before cruise day and then taking the shuttle from MCO to the port. Do we still have to pick a Port Arrival Time? What time should we catch the shuttle? Do we just show up and catch the Disney shuttle or do we have to set up a time (if so, how?)? Thanks in advance for any help!
