We recently brought our three girls here, and they had a blast. They are 4, 3, and 3 years old, and have since begged and begged to return, so we did! Lots of fun for all ages...they particularly enjoyed the grocery store, post office, and bank displays which offer hands on playing. They also like the bubbles and the working bee hive. Very cool! They change exhibits frequently so it is fun to return, and the price is reasonable at $4.00 a person. We purchased a Pals membership, so entrance is free, and they offer exchanges with other places each month. So in May, John Ball Zoo is free, and in June, the Meijer Gardens are free, etc. Definitely a great investment.
