Man, I would just sneak on…with nobody out there and thick vegetation to duck into should someone come whistling by, I figure in the early morning hours, if the irrigation is quiet, or during the lunch hours, when the island's asleep; one could walk along the beach wearing sandals and carrying a sunday bag, slip up the dune and play the 17th from the start of the fairway, then from there go to 3, 4, 5, 6, 7, 8, and your back to the beach. If all is going well and the putts are falling, you could play 9, 10, 11 and 12 bring you near the offices and the goon shacks occupied by sleeping guards, so skip over to 13, 14, by 15 and 16 you'll be near the clubhouse and her windows, so, I say after holing out on 14, hop the wall behind the green and follow the dirt road back down to the sea, where you'll run into a small wharf of diesel dingies run by shirtless fishermen. From there, charter one of the boats to take you back to Boao town, where a cheap beer and a rich story will be waiting….
But honestly, one could walk along the beach and play 17, 3, 4, 5, 6, 7, 8, and be gone, no problem, just remember to fix your pitch marks and replace your divots.
