From Western PA's review, Oahu tours & activities, fun things to do in Oahu | HawaiiActivities.com

Two great places to visit.

The visit to Hanauma Bay was spectacular. The snorkelling was wonderful. I have snorkelled many places in the Carribean, and this was so much better. My one daughter didn't care for the snorkelling, but the rest of us loved it. Even saw a sea turtle.

The visit to the Arizona Memorial was very sombering. Would recommend reading up about it a lot before you go, to learn as much as you can, and know what questions you would like to ask.

The duck tour from Hanauma Bay was good, but the one from the Memorial was a little strange. Weren't too sure about the driver, or the condition of the duck, barely moved.

Recommendations for all tours take the smallest amount of things possible. Sorry no pictures back yet from snorkelling.
