See that big P near the Orlando Premium Outlets?
Exit to the left out of OKW (Disney Vacation Club Way). Turn left at the light (Bonnet Creek Parkway). Turn right at the next light that takes you across Epcot Center Drive (I think that is Overpass Road). At the light when you get to the end of Overpass Road, if you went straight, you'd be going into Backstage Epcot. Make a U turn there and get on Epcot Center Drive to I-4 heading towards the Airport. Keep straight on Epcot Center Drive and it turns into World Drive. Pass through two lights and at the third light you turn left onto International Drive (if you went straight you'd go to the airport). Drive down International Drive and turn left at Regency Square Shopping Center. That is where the Publix is that you see on the map near Orlando Premium Outlets.
If you don't want to take Overpass Road, you can go down to Buena Vista Drive, turn left onto Buena Vista Drive, turn right at the next light and then another right just before you get to the light at Overpass Road. So either a U-turn or a loop.
Return the same way, but exit at the sign that says OKW/POR/POFQ, just after you cross over Buena Vista. You'll wind up at the light by Disney Vacation Club Way and Bonnet Creek Parkway. Keep straight and OKW entrance will be on the right.
You can also exit off this road before you get to Buena Vista, but you'll have to stop at the light at Buena Vista (right by the OKW Lighthouse). Go straight through the light to Overpass Road, turn right onto Disney Vacation Club Way.
This way you bypass all the mess by the Orlando Premium Outlets and the Shrine, plus all the timeshares along the way. And you avoid I-4 traffic.
