We did this excursion after our last cruise on Jewel because we had a late flight out of MCO. In my opinion, I wouldn't repeat it. They get you to Kennedy just as they are opening (so you wait in a long entrance line) - but the catch is they will leave about by 1ish if I am remembering correctly to get you to the airport on time for 2pm for people to catch 5pm flights. For us this made the day feel very rushed there and like we didnt really have time to see everything. If I was to do it again, I would possibly do express departure, and look into a one way car rental, drive myself and luggage and park at kennedy and spend the full day, which you could return very easily to MCO and then proceed from there.
