This place is a welcomed addition to Downtown Las Vegas. The building and its architecture are amazing first of all. I love the art Deco look of the Smith Center.
We had been here once before and came back probably a year later. This time we bought the family membership so we can return again and again. This will be great entertainment for the kids and with the exhibits changing occasionally we look forward to new and exciting adventures and Discovery each time we go. If you are a local go ahead and splurge for the membership. It will pay for itself after 3 or so visits.
The most fun the kids have is the huge multi story play structure and complex that has many things to explore in itself. Another popular with the kids was the Water World area. They could have played here all day and we look forward to playing here on a hot Las Vegas summer afternoon.
