If you are coming south from the Florida Turnpike, there is a new road called the Western Beltway which comes in by Route 50, and it takes you right down to 192 just west of the main gate of Disney to avoid Interstate 4. If you are coming from the airport, instead of taking 528 (the 'Beeline') to I-4, you can take 417 to the Osceola Parkway, or directly to 192, depending where you are staying.

Be aware that the busiest roads are the ones closest to all of the shops, restaurants and attractions: 192 and International Drive. If you are going someplace on one of these roads, you'll want to find out what major cross street it is near, so that you stay off the main drag for as long as possible (unless, of course, you want to see all the sights while traveling 2 miles per hour!) Some options to traveling along 192 include taking the 535 exit (or 536 into 535) off Interstate 4 which joins 192 East about halfway through, or taking the Osceola Parkway from I-4 to Poinciana Boulevard. Routes 535, 536 and the Osceola Parkway also head directly into Disney World to the west, so they provide a much easier route to and from the theme parks.
