It is a really fun place for kids 5 and older, or in my case a well coordinated 4 year old as well. The areas for younger then 3 1/2 leave a lot to be desired. If this place actually had a fun area to climb and explore (and be happily contained) for the younger siblings I would give it 5 stars.
As is, however, if you have a toddler expect to have to find ways to activity distract them so they don't get board with the toddler area. - update- they significantly improved their toddler area so i raised it up a star
