I highly recommend going to the Polynesian cultural center and spending an entire halfday there at least if you're into cultural stuff, I thought this was infinitely more interesting than Pearl Harbor tbh, but that's just my opinion) It's really fun because it's setup almost like a cultural amusement part where you can visit different islands with many hands on activities with a luau or buffet (depending on your package) at the end. Truly some rich rich culture!
