Hi all, we are booked on a back to back Caribbean cruise in December based out of Port Canaveral and are hoping to get to KSC on changeover day. The problem we're facing is confirming if we can. All the excursion information we can find tells us it's only available if you are disembarking as you are transferred to the airport after the excursion rather than back to the ship. Has anyone done this before that could offer any advice on if this is even possible? Thanks in advance.
