When you first come aboard the aircraft carrier, there's a station manned with volunteers who will assist you. Don't miss it: they are very helpful in explaining which of the self-guided tours are best for the interests and ages of your family/group.
Our 8- and 10-year-old grandsons had extra fun sitting in the cockpit of a fighter jet! :) I especially enjoyed the lunar capsule and accompanying radio transmissions. Hubby liked the deck filled with all sorts of aircraft.
Admission price is a little steep ($18 for ages 12+ and $11 for the kids) but it can be an all-day adventure. Snacks are available on board and restrooms are scattered throughout the ship. There's even an air-conditioned theater with a continously running movie, if you need to cool off or rest your feet for a little while.
Note for the motionsick: this ship is very stable. No rocking at all. It is permanently docked in the harbor. :)
