Start here and take plenty of time to see each museum. I've been to many museums including the Smithsonian and Normandy Beach museums and in my opinion this is world class.
One ticket purchased here, or at the other locations admits you to all.
I highly recommend this and I, in fact, would drive a day or more to see it. I can't say that I would do this about many other attractions.
On street parking with multiple hotels, b and b's and restaurants of all kinds nearby. See the TA reviews for the other museums such as The National Museum of the Pacific War. In reality, they are all one museum, which was based on this the original Admiral Nimitz Museum.
I would recommend an overnight visit for this. It is that interesting and extensive.
