A little costly, but so worth it. This museum is full of weird interesting things to see: from shrunken heads to torture chambers to the worlds tallest man. I would recommend NOT going here on a first date; unless you really want to freak out your date. (which can be helpful on some dates)
There were some exhibits in Ripleys that were kid friendly, but there were also entire sections that your family would rather do without.
In all, I enjoyed the cool things to see, but not the scary/freaky exhibits. Even after all the weird stuff that we saw, I would still recommend this place under the right circumstances.
