Just got off the Magic with an 11:20 flight out of FLL. We got in line to express debark at 7:45, went through customs, requested an Uber (3 minute wait), and pulled up to FLL at 9:02. Word on the cruise page was that it was an especially slow debarkation, so I think having all your bags with you is key because you just never know how smoothly things will run day of.
