If you select a single order with two tickets, it will work. In this scenario we are assuming it's your significant other.
If it's a buddy tell them to register separately so that you don't have to fight to see who gets the prize should you win!
Please remember that each person must read & agree to the waiver / indemnification form. You can sign one in person the day of the event or by registering online you are accepting all the terms and conditions.
Here's a link to the waiver:
