My dad and I are planning to go to Tampa and stay with my cousin the weekend of the national championship. Obviously we are hoping the Buckeyes are in it. Only confusion is can we buy tickets after the Semis? Do we have to buy them before? 

The myticks thing our whatever is on the CFP website seems like a scam.. spend hundreds hoping the good guys win.. and if they do win then we can buy face value tickets, but if they lose we are out the money and still don't have tickets to sell in Tampa. Anyone have any tips for us how to go about this?
