We took the bus from the neighboring Swan to MK for an 8:15 CP reservation on a non-EE day. We were at the bus stop around 7:30 and it only took about 15 minutes to get to the park. We were able to take our time and get some pictures on the deserted Main Street. I would recommend taking the bus, so you don't have to hassle with parking, walking to and from your car, and catching the monorail.
