The vending machine for the sodas are 1.50 and they accept credit cards.They have some small snacks in the gift shop like chips and candy for $1.00 - $1.50.I hope this helps you out.I was just there today with my family for a field trip and got all the prices for everything.
They have a vending machine that has soda water and Gatorade but I don't remember seeing a vending machine that has snacks
Don't think so.
