We went a few years ago and it was a great way to spend a couple hours. We had a lot of fun. Oddities and a few things that I don't want to tell because it would spoil someone's fun. We thought it was worth the price. Look for discount coupons, though. It's definitely NOT Disney caliber.
I thought it was ok, dh and I went together before the kids were born, Some stuff in there was pretty neat. THey have a website, I don't know if it's Ripleys.com, I think so, it will show you a few things inside.
We went to the ripley's in Orlando. It was a lot of fun and we bought little shrunken heads afterwards. It had some very odd things in the building. We just got a ripleys here in panama city but after going to the orlando one the ripleys here is definately not as good as Orlando's...
We haven't done the one in Orlando. We have done the one in Gatlinburg and Niagara Falls. I think they're just "okay". If you really have nothing else to do- it can be amusing. However, I don't think I'd actually set aside time to plan it in.
There was lots of mocked up exhibits and photo's w/ Ripley's Believe or Not type facts. A lot of the stuff you've seen on TV. There are some trivia questions here and there. As well as a few hand's on type things.
