We’ve had flights around noon and made it without any problems, that’s was before we had TSA Pre-check too. We always have early dining for dinner so that gives us the first dining period for breakfast. After that, is when they start to debark and filling the busses for MCO. I don’t remember what time we usually get to the airport, but I’ve never felt stressed about it, and I’m a gotta get there early and wait kind of guy.
