This is a fun attraction in Las Vegas. It's located on the Las Vegas Strip just outside the Venetain. I think it's great because you can get up close and personal with the figures. You can take all the photos you want. They have staff who are stationed at specific places taking photos which you can purchase at the end of the tour but they don't push you to do it and they will take the photo with your camera as well.
The tour is self guided which is fun because you might want to spend more time in one room over another. They have two floors with a lot of interactive stuff including a Scream scary attraction inside.
Overall, I think it's worth the money and it is one of the few things you can do here in Vegas with your entire family.
