Our son went to Artsy Nannies at Town Square for a few hours while we hit the slot machines. He had a great time. He's older than a lot of the kids that were there (he's 11). The woman working (the owner maybe?) had her son who is our son's age come hang out with him. He loved it and made a new friend.
Booking was super easy. The price can't be beat. It's a short drive to the casinos on the strip. The place looked clean and well-organized.
We will definitely use Artsy Nannies the next time we're in Vegas.
