The way I usually get there is to take the South Exit fron the airport to 417 tollway, stay on that to the International Drive exit #6 (first WDW Exit) continue straight past I-4, and enter Disney property. I think it is the 3rd exit once you are one Disney property. It will say OKW and Port Orleans. Remain in the center lane on the exit and go straight at the signal (for POR you'd turn left). The first right is the CM/housekeeping entrance, the second right is OKW, 3rd right is the treehouse villas, then SSR.
