You could take 528 (though that route will probably be busy, too) from the airport to the International Drive exit, turn left onto I-Drive, get into a righthand lane and continue toward SeaWorld, turn right onto Central Florida Parkway and go past the SeaWorld entrance, stay to the right and continue straight under the I-4 overpass to the end of Central Florida Parkway, turn right onto Turkey Lake Road and continue to Universal (which will be on the right -turn onto Hollywood Way). Turkey Lake Road parallels I-4.
