You most likely will be fine.. but it's up to you if you want chance it, you never know if there is traffic, or the ship is delayed.....but I would do self assist and book private transportation, we fly on jetblue which is in the international flight terminal at MCO .. terminal C , and we were off the ship by 730am, and at the airport by 9am. The 2 times I have been in terminal C.. the security lines have never been long.. usually around 10-15 minutes tops, and the 1st time was at 930 in the morning and the 2nd time was 5pm ... it was the fastest TSA checkpoint I have ever gone through., and I don't have TSA precheck.
