I think I’m in the minority in feeling this way, but the driving didn’t bother me in the least except on the North Shore when looking for parking. In every direction there is incredible beauty and interesting sites. Too, the drivers on Oahu all seemed so chill, nothing like what I experience at home. Drive H3 at least once.
I agree 100% with not trying to adjust to the time change. There’s so much to do in the morning and not so much in the evening.
If you visit the Windward side, make time to just drive that side of the island. Read up on sites to visit—stop at Byodo-In Temple, beaches, Laie Point, food trucks, Tropical Nut Farm, etc. It’s beautiful and relaxing.
Island Vintage Coffee and Island Market (ABC store) across the street from Aulani have good food options, not to mention Monkeypod and other food options.
