While the airport can be very busy there are two sections of TSA for security gates 1 -59 and 70-129. You will then take a train to one of 2 terminal areas within your gate section! Be prepared for long security lines here, although the clear and pre-check lines move quickly!
What makes Orlando International Airport a great choice is that there is an airport hotel inside the Airport – the Hyatt Regency MCO great for those with super early morning flights or late night arrivals!
The main terminal is broken up into an A side and B side within the main terminals with a ton of shopping and a large food court as well as restaurants with plenty of seating! And more shopping and dining options once within your gate area like Cash and Larder, Outback, Hemisphere and more!
