I think it's always quicker to drive yourself on property. TL is close to DTD and perhaps your quickest route to MK would be to get on a Contemporary (or Polynesian, or GF) bus and then travel to MK. From the CR I would just walk over, boats or monorail from Polynesian or GF. If you decide to drive, you will tram to TTC, and then ferry or monorail to MK.
