I think Rod posted this elsewhere, but I wanted to add it to this thread to clear up any confusion:
Pre-registrations lets us and everyone know that you are planning to attend the event. You do not have to pre-pay for the event at the same time you pre-register. After you are pre-registered you can pre-pay anytime until registrations are closed. But please note, you must pre-pay to guarantee a seat. If we fill all available seats by pre-paid registrations, only those registrations will be allowed entry to the event and also only pre-paid registrations qualified for the discounted entry fee. If you are pre-registered but did not pre-pay then you simply just have to pay the "at the door" price when you arrive at the event. If you would like to pre-pay after already pre-registered, you will be reminded on our home page or simply visit the registration page again. It will keep you updated on your registration status.
