I'm so glad to hear that. My heart would ache for you if something were to go wrong. I'm sure it can be done, but I would hate to be under that much pressure when returning from a wonderful cruise.
If it were Ft. Lauderdale, much more doable since you're literally across the street from the airport. Heck, you could walk if you had to. Maybe they'll build an airport closer to Port Canaveral one of these days?
