Overall, this exhibit is worth a visit, even for someone who thinks they have no interest in the ship.
They have rooms full of artifacts found in the debris field (including things like dishes, jewelry, and handbags). The highlights were definitely the large section of the actual ship they have hanging up and the replica of the grand stair case. There are detailed descriptions and signage for every item.
Minus one star for the steep price tag and some of the museum being a little repetitive. After about 7 exhibits of plates, it gets a little old. Also, I happen to think the gift shop is tacky at the end.
