This attraction is open daily (except Christmas and Thanksgiving) from 8:30 a.m. to sunset. Admission is free to the Military
The first machine is in the gift shop, no admission necessary.
The second machine is past admission, but we were allowed to access it without having to buy a ticket by the nice ticket seller.
