Oahu, Hawaii - Things to do?

Hi, We're staying for eight days during June 2012 at a beach house on Laie Beach. I have my wife and children (girl 7 / boy 5).

So far we plan to:
- Obviously snorkel and swim at the beach house.
- Get shaved ice at Matsumotos.
- Get a burger from Kua Aina.
- Visit Pali lookout.
- Go to Benihana restaurant.
- Visit the Dole Plantation.
- Visit the Polynesian Center.
- Visit Pearl Harbor / USS Arizona.
- Hike at Diamondhead.
- Snorkel at Hanauma Bay.
- Visit the International Market Place.
- Shark cage adventure on north shore.

I would like to find a place that I can jump off a cliff into the water (moderately small cliff / rock). We plan to eat most meals at the house to help keep costs down. We're looking for other things to do during the daytime that will be fun and memorable for the children. We have already bought all of our snokel gear and a Nikon underwater digital camera.

Go to a luau!

Plate lunch from Yummy's Korean
Pali Hwy Lookout
Do H3 going towards KBay view from coming outside tunnel is incredible

Some of those things can take all day so you do have to take that into consideration. Just do a drive around the island which can be interesting itself.

Go to Lanikai beach… Best on Oahu and the place to jump off a rock into the ocean is at Waimea beach park. I have seen it done there but didn't do it myself. Have a great trip.

Go to waimea beach for a jump off. And maybe go to the shrimp farms, hike up diamond head
