Tumble drum is a place that is filled with slides, tunnels and ball pits for kids to romp around in. They have security features that do not allow kids to leave without the parent and for them not to be able to leave with the wrong person. They have a restaurant inside where you can order pizza or get a latte. The cost is extremely reasonable ($4.30 for one child) and the kids love it. The only thing that detered me from giving it the full 5 stars was the fact that it had stairs that were a problem (kids running into each other) and the carpet was pretty nasty. But as long as you stay on the first floor ou are okay. I would say it is best for kids 5 and older.
