looks pretty intense for me. And you switch hotel too, probably pack light would be more convenient.

PCC is close the waimea fall. Actually there is TAO luau at waimea fall, maybe skip PCC and choose tao luau.

Hanauma bay needs reservation, so set a reminder on your phone for that. they release the slots two days ahead at 7am. normally by 7:30, all slots are gone. you should aim for earlier slots, since the water will be calmer. we spent whole day there. beach is closed at 3pm.

PCC is bigger. Tao has a limit of 100 people i think. so it's more intimate.

Other than that, thecultural experience stuff is pretty similar. You can check tripadvisor for more review for references.

for smaller kids, the zoo is pretty nice. my 10 year old one loved it. she saw quite some birds she only saw in books before. Wakiki beach tends to be busy, but a little further south it will be much quieter, like queens beach and kaimana beach. kainama beach is very quiet and we saw seals there sleeping.
