It depends on what time your reservations are. The boat to MK starts, I think, 45 minutes prior to MK opening. If it is an early magic hour, it will start 45 minutes before that. If you need to get there before that time, then take the other, smaller boat that goes between the Contemporary, Wilderness Lodge and FW. Get off at the Contemporary and take the monorail to MK. These boats start running earlier than the boat to MK. These boats load at the same dock as the large boat to MK, it's on the right side of the dock. I would do this before I would drive.
