Hawaii Restaurants Week

What fun things are there to do in Honolulu on Oahu, Hawaii?
My husband and I are going to go to the Hilton Hawaiian Village Resort and Spa for a week in Honolulu and were wondering if anyone had any suggestions of restaurants, snorkeling places, ropes courses, fun beaches, etc for us to do without going broke. Any suggestions? Thank you!
There’s actually four sections of Oahu (going by shores):
-North Shore
-South Shore
-East Shore
-West Shore
(This has nothing to do with my answer, I just wanted to correct the third poster).
Anywhoo, you can buy an entertainment book, which is FILLED with coupons for everything you can imagine. Yes, you gotta pay for it but it’s worth it.

After buying that, you can do whatever you want without going broke. I highly suggest you and your husband head out to Ku’aloa Ranch to horseback ride, go ATV’ing, kyaking, etc. It’s a lot of fun.
