There are a ton of activities that you could spend all day doing. However, there were so many people, on a Saturday, that it made it not fun. There were kids not following the "rules" so little kids got pushed around, even on activities listed for the little ones. But there was plenty of things for kids of all ages to do.
The animals cages were not well cleaned.
The maze was well thought out, because they had different levels, so you could just go for fun and be out in 20 minutes or you could spend hours on the big challenge.
I would suggest not going on a weekend. Plus, it was better suited for kids like 7-13.
