The only problem is that FFL is something like 3 hours from Port Canaveral and Miami is about another hour away as opposed to 1 hour. This seems to me to be much more of a hassle, and probably much more expensive. you know what you want better than me, but if it were me, l'd do it the way that your daughter wants to do it. All in all, I'm sure that you'll have a great cruise. Enjoy!
