A car is the best way to get around if you are not staying on Disney property. If not a taxi will cost you.
There is no I-92 anywhere in the United States.Now if you want to be on US 192, follow the signs out of Disney towards US 192 and then head east.
leave Disney area and go onto I4 and come off on 192, that s the way we go anyway. hope I helped.
why would you want to leave?
