While most activities require that you bring a printed copy of your confirmation paperwork as proof of purchase, there are a couple that do require a separate voucher – Mount Rushmore for example. Your confirmation itinerary that is automatically emailed to you when you hit reserve will indicate any vouchers that are required. There will be a link to click on above your contact information for Vouchers. You are also more than welcome to call us at 605-578-7702 & we can help you out.
