World YoYo Contest Question

I am going to the world yoyo contest in the morning and should arrive about 9:30. Would I have to be registered online to get in? Or can I just pay for admission to get in at the door. I am NOT COMPETING, so ill just want to watch and buy yoyos and stuff. This is my first big competition. So I don’t know if I need to register online to get in or can I just pay at the door since I’m NOT competing. Thanks in advance.

You can register and pay at the door since you are just attending and not competing:
