First off, if you have young children or can't get around too well, I recommend you do NOT go to Patriot's Point. You have to do a LOT of walking, and along with the heat, it can be very difficult. Also, my wife, daughters, and sister-in-law got very bored. Not to be stereotypical, but men would probably enjoy this trip more than women.
At Patriot's Point is World War II and Military aircraft displayed onboard the aircraft carrier Yorktown. There are twenty-five aircraft, four ships, and a medal of honor museum. There is a mock Vietnam Naval Support Base, which shows the living conditions used by Vietnam support base veterans. There is a 31-foot River Patrol Boat, ammunition bunker, combat information center, 24-foot gun and observation tower, Huey UH1H Medivac helicopter, displays, artifacts, and authentic weaponry at the site.
Onboard the Yorktown are: SBD Dauntless, TBM Avenger, F6F Hellcat, FG-1 Corsair, N-2 Stearman, F4F Wildcat, B-25 Mitchell, TF-9 Cougar, McDonnell-Douglas A-4 Skkyhawk, UH-34D Seahorse, S-2E Tracker and E-1B Tracer, AD Skyraider, F4 Phantom, A7 Corsair, F-14 Tomcat, A-6 Intruder, SH-3 Sea King, AH-1 Cobra, UH-1 Huey, and F-8 Crusader.
There is a snack counter and gift shop before you get to the touring area, and an authentic Navy cafeteria in the Yorktown (the food was actually pretty good!). If you are a World War II buff, or just like military stuff like that, then Patriot's Point is the place for you. It's not for the fragile though, as there are tight spaces and rough climbs in some areas, especially on the subs!
