I didn't see any discounts for large groups. Though if you installed the Giant Food app on your phone, they were giving 50% off of the second ticket purchased.
Check website
I dont work there. I was just there. They didnt offer discounts. Adults where 30 and kids 12 and under half price. It is worth every penny. Gift shop prices are impressively fair. Museum entrance is free with purchase of ticket. Has a maze and actual gem mining.
