Yup - drive to the TTC and go to the MK monorail. The CM's there will look up on their list to confirm that you have a PS, then they'll let you on the monorail. At the MK main gate, you'll see a sign (or just ask) for the entrance for people with an early PS. Again they check you off on their list and your on your way. The best part of this? You will have Main Street almost all to yourself. When we did this last year, we saw absolutely no one between the gate and the castle. Great photo op!!
