I visited the Hornet and stayed till one hour before closing. The were giving tours as I departed. If it's not busy (and probably isn't) they will give you a tour upon arrival if you request one. In other words, they're very friendly and due to the lack of people showing up the guides have nothing to do, they would love to give u a tour at any time.
The ticket is open ended. You just show up during open hours. No set tours but plenty of friendly and informative docents that served to show you around and answer questions. For now the flight deck and and below decks are closed. Just the main hanger is open, but it has a lot of cool planes to see.
