If you're in Nassau and don't want to spend a lot on pricey excursions this museum is a great alternative. We were all impressed with the displays and the information that was new even to me - a history buff. Even if your interest in pirates is minimal - the history of the island is quite interesting. I would say, though, that you really do need to stop and read everything to get the most out of the museum - a walk through would not do it justice.
The fee was $12 for adults, but anyone under 18 is considered a "child" and pays $6. Well worth the entrance price.
