ive never parked a car at magic kingdom and I understand we park at t&tc but do we walk from there or take monorail? Are there trams?
When you drive to the MK, there will be CM's directing you to a specific area of the lot. When you park, note whether you are in the "Heroes" or "Villains" section, the character, and the row # (important info for finding your car later!).
When you leave your car, follow the crowd to the tram loading area, and follow the CM's instructions. The tram will take you to the TTC! (While it is possible to walk to the TTC from anywhere in the MK lot, almost everyone takes the tram. Sometimes families with strollers choose to walk because of a sleeping baby, and/or to avoid having to fold the strollers for the tram. Others just like to walk, I suppose.)
When you arrive at the TTC, you will disembark from the tram, and go through a security check. Now you are ready to travel to the MK!
As mentioned previously, the options to the MK from the TTC are the monorail (resort or express), the ferry, and possibly buses. There is no option to walk from the TTC to the MK.
(Frankly, compared to the other parks, it is a huge PITA to get to the MK gates from your car, but it is what it is.)
