It had been almost 30 years since I went through the Nimitz museum and back then you could see everything in about 30 minutes. Like I said, it had been about 30 years and today, I was amazed how large the museum has grown and believe me, it would take a heck longer than 30 minutes to see everything. You can look at a minimum of a couple of hours if not more. It is well planned and gives you a history lesson before WW1 to WW2 and beyond. The exhibits and interesting if not amazing. It is well worth a visit of all ages within reason meaning 12 to 100.
