Arizona is a couple hours and by Pearl Harbor. You can rent a car and drive there or take a tour. It is best to be there early and you wait in line and then watch a movie, then boad a boat that takes you to the Arizona.
You can NOT carry a purse or backpack, can't remember if you can even take a camera. It is free.
The Poly. Cult. Center is way around the island the other way and is an all day event. You can drive there and pay and go in and pay for dinner there or not. OR you can take a tour from your hotel. It is a pretty interesting Morman run set up and a must see...just allow yourself TIME there and dress in layers.
