This children's museum is amazing! So many areas with a variety of activities catering to different age groups keep the options interesting. I love that they have a new traveling exhibit available every 4-6 months to add to the excitement of a visit. My children are young so there is quite a bit beyond their interest/ability, but still plenty to do for several hours. We opted for the annual family membership, which I found with several visits paid for itself and was well worth it. For the under 2 yr old crowd there aren't many options. But if you have a baby in tow, there is a nursing nook in the pre-walker area (Yay for nursing friendly!) This is one of our favorite family friendly places in Las Vegas.
