I also believe it is $12.50. And it is well worth every penny!
The admission cost is $12.00 per person ages 11 and up, ages 5-10 is $10.00, and ages 4 and under are free. After the guided tour the pass gives you $10.00 discount on an item in the gift shop, one pass per item.
12.50 per adult I belive but it's been a few months since we where there
