I love autocorrect.
I want to be walking through the doors of the airport at 2 hours before my flight. Not parking, not in an elevator, not pulling up, but walking in.
I know what you mean about feeling like you ran a marathon; I just hate getting sweaty having to rush rush.
But, you know, I find that even walking in 2 hours before usually ends up with me rushing, and I generally get to the gate maybe 10 minutes before the boarding announcements start. And MCO has been highly unpredictable for us. Add to that that they haven't let us into the experienced travelers line with DS (who is more experienced than many people getting into that line) and it often takes longer than we expect.
Definitely look up the official website for the airport, and see what's available.
