Yes, using online checkin usually allows you to go straight to the car. You can also checkin at the kiosk and save a bunch of time, at locations with a automated kiosk. Orlando has both kiosks and online checkin available, but I don't know if they have "go straight to the car" online checkin. I've never used it at Orlando. I've done it at other locations where we just walked straight to the car and got in.
