Just got back. If you do drive, highly recommend get Guide along GPS tour. Lots of good info, sites and history. And the Narrator's voice is so soothing.

As for the North Shore, driving is a mess. Construction has areas down to one lane so lot and lots of sitting in traffic not moving. We gave up this trip because we had already been, after sitting in traffic forever and not getting much past Turtle Beach after visiting our friends in Haleiwa
Some other things I recomend not in Ko Olina area.
If you are going to be by Jurrasic Park ranch area, Get some Huli Huli Chicken. You will see the smoke out front as the turn the chickens.
Discover delicious, locally owned Huli Huli Chicken in the heart of Hakipuʻu at Coral Kingdom Shopping Center. Open daily with friendly service.

Place that looks like it is going to fall down and huge line of locals
We took a bunch of folks for a Chocolate Tour so if you want to try Chocolate from the North Pole of Chocolate - Oahu is technically too far north for Chocolate, so the Chocolate compensates by producing more Cocoa butter so the taste is amazing.
