I have been before, a few years ago and I enjoyed it. I guess it is all in what you like to do. Personally I really enjoyed the "crime museum". My step-daughter and I really ate that up, her probably more than me even. It was very interesting and well worth it.
I know they have a Titanic museum too.... I haven't been to that, but I have been to the one in Branson. If it is anything like the one in Branson (which I would assume it is), it would also be good to visit. I am kind of a Titanic nerd anyway though.
But again, it all depends on your individual tastes.
