I could literally spend days here.. LOVE the exhibits, the stories and the artifacts. I also loved that this is the original courthouse where the inquiries were held and that they incorporate that history into the tour. Make sure to leave yourself plenty of time as it's three floors and there's lots to see, read and interact with... definitely time well spent!
It is a timed entry musuem and it was very crowded when we went so be aware that you can buy tix online. Also, the parking lot is WAY too small and not free.. we had to park at a nearby casino parking garage and walk a bit but it was actually cheaper than the musuem's tiny lot.
Also a slight trick I figured out.. if you buy a membership for $25 you can buy additional tickets for the local price which is only $10 so for two people you can go in for $35 versus the normal $40 for 2 people entry fee and one of you will walk away with a year's membership! You can thank me later. ;-)
