Feedback on 9 day itinerary for first time visit with a 5 year old

I'll be traveling to Oahu for the first time next week with my husband and our 5-year-old son. We want to experience a good mixture of city with good dining options/nature (all that lush jungly feel). But my son gets pretty tired with lots of car travel. How does this itinerary look? We'll be staying in Sheraton Waikiki. Anything that we should leave out/something that is missing? Also, any tips for foods places when you just want to grab something quick but tasty in Waikiki would be welcome. Thanks!
