There is only one road to leave the airport. You will come to a stop light about 3/4 mile after you leave the airport terminal. Veer left onto Dairy Road. (You will see Costco, then Kmart on your left). After about 1 mile on Dairy Road, you will see signs to Kihei or Mokulele Hwy. Turn left here onto 311.
After about 6.4 miles on 311, it will turn into State Highway 31 (aka the Piilani Hwy). Stay on the Piilani for another 5.4 miles until you get to Keonekai Road. Turn right on Keonekai and follow it 0.6 miles until you get to Kihei Road. Turn left on Kihei Road and go 0.2 miles. Kihei Shores is on the left. Take the long driveway into the complex.
The “A” building is the first building on the right as you drive in. So, as you drive in, take your first right and park in Space #94 if it is available. If not, park as close as you can to #94 without parking in any of the “reserved” spaces. A304 is on the 3rd floor just above parking space #94.
