I used to park in the terminal parking (East or West structures). Usually around level 2. I'd us a space between a regular space and a structural pillar. Any vehicle parked in the space could open their door fully without coming close to the bike on the center stand. Would park it there for days at a time.
The advantages are that it's close to the doors/elevator, covered parking, and the space is just right!
USAirport parking doesn't take motorcycles. Don't know if Canopy will or not.
