Take a walk down Waikiki Beach at dusk and stop at the Royal Hawaiian Seaside Lounge for a drink. They have live music and a beautiful hula dancer.
A must is a trip to the Arizona, Pearl Harbor Memorial. It is a very somber place, and the people at the memorial are very helpful.
Take a walk to the Ala Moana Mall. They have a wonderful food court--very inexpensive and healthy food, as well as a lounge in the center of it. The shopping isn't too bad either! GREAT STORES!
Another place we enjoyed was a ride up to the Pipeline and seeing the tremendous waves. Another must is checking out all the beautiful beaches and the different-colored sand at each one.
Also, the sunsets are absolutely beautiful, so take the time to enjoy them!
Quick Tips:
We purchased an entertainment discount coupon book before we left Rhode Island and found it to have some great coupons. Also, the hotels and resorts offer discount coupons on different attractions. And we found it very helpful to ask the locals for suggestions!
Also, be sure to get the local newspaper--it is full of things to see and do!
Best Way To Get Around:
We either used a rental car or walked to get around everywhere. Some people did use public transportation; however, they did say that it was very slow, and time was wasted because they had to wait for the bus to return from different attractions and malls.
