Be careful and continue to check on your reservation. They can charge you full rate if they want to. Remember you are paid in full, but it's on a discounted rate that you do not officially qualify for. As mentioned on the boards, they may ask you for the pin or the printed email or mailer when you check in.
Not exactly the same, but airlines have the right to ask people to buy an extra seat if they feel the persons size requires them to have an extra seat not only for their comfort but also for the people sitting next to them. If the person doesn't want to they can just refund their money.
I'd hate to be all pumped for the trip, get there to check, and be told it was going to cost me rack rate to stay there.
Please keep us posted when you do go what happens.
