I was on the Midway 2 weeks ago with my 9 year old son. GREAT time - took the wonderful self-guided tour. He was able to earn his Junior Pilot wings by answering questions in a pamphlet they gave us when we came in. He loved it! Very cool!
Had a much older brother serve on the Midway until it was decomissioned. He then retired abroad and passed a dozen years ago. I did the excellent self guided tour of the Midway in 2008. It was fascinating and also gave me a chance to connect with a brother I hardly knew.
