Things to do during free time
I'm going to be taking this tour this summer. It looks like there is a lot of free time. I'm not someone who just sits on a beach. Any suggestions for what to do during free time? (I will be arriving a day early and will spend a day on Ford Island in Pearl Harbor, where my father was stationed during WWII.). I've been to Oahu and Kauai many years ago, but don't remember a lot.
