Not to thrilling for my 4 year old grandson. A bit to old. Maybe about 7 or 8....Not worth 20 bucks admission. Was $93.00 for 4 adults and a young child age 4 and a infant. Some of the displays look like they were developed in somebody's garage. Was kinda dirty, But it was interesting and educational. There were parts that really were well done. I just cant understand why it's so low budget for what they charge..Maybe most of the money goes to salaries of over paid executives!!!!
