Storing luggage after cruise for late flight?

[tvguy]

That was a fluke. I've flown out of MCO seven times since June 2017, and never had any issue with security.

If you Google "how much before my flight should I arrive at MCO" you will see that even the airport recommends being there 3 hours before your flight.
So to be most helpful to the OP, some have arrived less than 3 hours before flight time with no issue, but some of us have not and the airport itself recommends 3 hours.
