At park opening times the traffic can be fairly heavy, depending on what time of year you plan to go. Mid-November is a good time to go. It should take you about 15 minutes to get to MK parking, and about 20 minutes to get to AK. Keep in mind that you are still not at the parks at that point. At AK you will walk or ride the tram to the entrance plaza. Add ten minutes. At MK you will park at the TTC, leaving you a tram ride and then a monorail or ferry ride to the MK turnstiles. Add another 30 minutes to the trip.
