If I don't get to the airport AT LEAST two hours before the flight, I'm a nervous wreck. I've gotten to the airport with what I thought was PLENTY of time and BAM! there's a big tie-up at check-in, security, what-have-you and I've barely made it to the gate.
With the way traffic is in Orlando, I also have to factor in road delays. Accidents, roadwork, exits and entrances being closed. If parking at the airport, I have to factor in parking and taking the shuttle to the airport if parking off-site or driving around in the garages looking for a spot.
I'd rather stroll in leisurely, not sweat it, check in, get through TSA, wander around a bit, look in the shops, go to the potty, have a snack, people-watch, go to the potty, go to the potty again, etc. I really do enjoy people-watching. Sometimes, I strike up a conversation with someone and I always enjoy that. I'll have a book along. The phone is charged.
An airport is never going to be as exciting as a train station, though, at least the train stations in the old days. My grandma and I used to catch trains to go places. Great big marble edifices with towering ceilings, really important sounds echoing off them. People scurrying around. Soldiers and sailors sitting on their duffle bags. Very important announcements such as: "Now loading on track mumble-mumble, for mumble, mumble, mumble and points west!" Somehow, people seemed to always know which mumble was their train.
