We visited this battleship on a Wednesday in late August 2008. We visited an aquarium in the morning, then went here about 2:00 pm. I think we toured for three hours, but could have easily spent the day. My kids were 7 and 11, and were fascinated by this. I thought they would like it, but every family group on the ship was having a good time.
First, watch the movie history and look at the exhibits inside. They are well done. My grandfather was a diesel mechanic in the Pacific theater in WWII, so these exhibits were very moving.
Then move onto the ship. There is some walking, but I am mobility impaired and could see three levels of the ship without trouble. Almost all of the exhibits are interactive. If you're not supposed to touch it, the room is behind plexiglass. Everyone in the family was fascinated by the compact, efficient layout. The signage is fantastic. Easy to read, well written, and informal. I learned a ton about WWII and how wars are run.
My kids crawled all over this ship. My daughter was thrilled that this ship made ice cream, and insisted that I take a picture of her in front of the ice cream shop. That's her 'making muffins.' My son is 'shooting down the enemy.'
As we were getting ready to leave, an enormous alligator cruised up to the side of the ship. Evidently tourists feed her sandwiches and she was looking for a handout. This was our first live wild 'gator sighting, so was very exciting!
The gift shop is blessedly air conditioned, but sparsely stocked. I would have liked to buy my dad a book about the ships of WWII, but they did not really have anything.
Admission is typical-- $12/ adult, $6/ child 6-11, free for kids 5 and under. I just found out that admission is 1/2 off for ADA, but we paid full price for me. This is definitely worth it, a highlight of a great trip to North Myrtle Beach.
