There is a Costco. I don't have the instructions from the airport. From Disney if I can remember right you ( we did this from OKW) you go out to 535 from downtown disney I think this is called Winter garden Vinland. make a right, go down to International drive (sr 536) and make a left. A little ways down International drive will bear left. You go straight, this is the entrance to toll 417. You get off at the second exit (exit 11). It is a $1.00 toll. Make a left onto us 17 It is on the nw corner of us 17 and Waterbridge Blvd.
The distance from the right turn onto 535 to Costco is about ten miles.
If you are coming from the airport, take Bee Line (528) and get off at us 17. I have no idea what the signs say. The ramp will exit onto CR 527a. Make a right and when you get to us 17 (a little over a tenth of a mile) make another right. total distance from exit to Costco is about 2.5 miles.
ALL THIS ACCORDING TO DELORME STREET ATLAS PROGRAM.
You can go to the Costco sight and get the address, then go to mapquest and put in the origin and destination address.
