I've been to many Chevrons (sadly not all of it but I couldn't manage to come twice the year) and enjoyed the organisation, the great and funny guest and of course the fun to meet so many nice people. But I can understand why less people are coming because I also fell in love with so many new shows over the years.
Maybe you already tried it and it didn't work out but I think it would be better not to announce all the guest so early. Other organisations are announcing their guest one after another over the year and everytime there is some new chatter about this event. I was happy to see all the great guests for 2015 at the Chevron 8.1 and bought my ticket on that sunday but over the year there was nothing more to wait for besides now the hotel code.
To be honest reading your post again (I also read the first one some time ago), Jason and waiting for the hotel code make me feel insecure about this event. I know that I will get my money back for the ticket if the event is getting canceled but I don't want to book a flight now, coz I'm afraid I might loose that money. I hope you can sort everything out soon and can tell us the code for the hotel.
Have a great start into the new year and hopefully see you all soon!
