The Tahoe Tot Spot is one of Nate's favorite places in town. They have numerous rooms such as the art room, train room, dress up room, puzzles and books room, and then the large area in the front with gym equipment, trampoline and ball pit. I love it when my kids go here to because they normally then take great naps! Its not super cheap though so we just go on special occasions.
Here is a short video of my crazy kids.
