Never going back, total waste of money
The clerk was nice if your questions are just about the cave.
When I tried to explain that her sign '$10 Minimum Purchase on use of Credit Card' was against both Mastercard and Visa merchant policy, she got very mad and snapped my head off.
She also could not wait for the children to leave the gift shop area, which makes it very unfriendly for families.
The tour was just headsets, no one to lead and/or ask questions.
I would not recommend it to anyone, everywhere else we have visited in the state was friendier and there are better caves to visit.
