MCO parking
MCO parking is month-to-month ($34). To get to the office that issues passes, go to the JetBlue ticket counter. Walk west until you pass a main hallway into the terminal. I can't recall the company that ownes the ticket counter just pass that entrance, but behind it is door that has a small sign about admin offices. Go in that door about 30 feet and you'll see the parking office.
Don't know if your company has to have a presence at MCO.
