The museum itself is nice and very educational. I'm very impressed! Don't forget to go on their tower tour (located on the back of the ship) that takes you up the control tower.
They have many volunteers and veterans that tells you about their experience on the ship. They usually hold mini lectures at different places, which is nice.
HOWEVER, this ship also has a ton of veterans who are allowed in for free, and they stop you to make sure you know their terrible past. They hang out on the deck and hangar levels and talk to people nonstop... and gets annoying really quickly. If you don't like to hear about people dying and such, don't even talk to them.
This museum is definitely worth visiting, but only for once or twice. It could get boring if you kept going there.
