TTC is the ticket and transportation center on Disney property. It is located across the lagoon from Magic Kingdom. If you drive your own vehicle to MK, the parking lot tram will take you to the TTC, and then you will either take the monorail or ferry over to MK. You can also take the monorail to any of the MK resorts (Contemporary, Polynesian or Grand Floridian) from the TTC. And, as stated previously, you can catch the Lynx bus at the TTC. When we stayed offsite, our resort offered it's own shuttle bus, and it also used the TTC for drop-offs and pick-ups.
