Im not 100% sure, but once you are in there is a station where you can sign up and get a chance to win free stuff. I'm assuming that is for people that arent a member or paid to get in. From what I understand as long as you are a member prior to MAY (or was it March?) you get in free, so im assuming if you sign up now you're in free. Don't quote me on that, I'm just a guy on the internet
