Kennedy Space Center Visitor Complex — Independent Full Day
Stand beneath the actual 363-ft Saturn V moon rocket, walk under the flown Space Shuttle Atlantis suspended mid-flight, and ride the bus tour past active SpaceX and Artemis launch pads at the real working spaceport. It's about 15 minutes from the cruise terminal and comfortably fills a 6-8 hour port day — the single thing Port Canaveral is famous for, and the one a first-timer should not skip.
