You take a tram to the TTC and then take a monorail or ferry to the front gates.You can walk to the TTC instead of taking the tram,the thing with that is that the lot is very big,if you're parked up close to the TTC then it's worth walking,but if you're way back by the racetrack I think the tram is the fastest easiest option.It all depends on where you park.Epcot for example offers a tram but the way the way the lot is setup I find it easier to walk.
