Play Kapalua Plantation once for the views, shots, and nostalgia. After that, drop the clubs.
Hike to the Iao Needle, snorkel a bunch, jump off the rocks by the cliff house at kapalua, surf, rent a paddle board and try your hand at that. Drive counterclockwise around the northwest side to Kahakuloa and get some of Julia's banana bread. Get macadamia pancakes at The Gazebo. Stop by the Fish Market Maui in Honokowai around 2-3pm and get the freshest fish they have (likely just an hour or so off the boat) and go next door to Maui Brewing Co and grab a growler of Coconut Porter. Go to a beachside outdoor grill and watch the sun go down with great local beer and fresh ono sizzling as your lovelier half beams. She'll appreciate you more and you'll earn credits with her to spend on way better golf courses once you're back on the mainland.
