The best thing you can do then is sign up now and mark that date on your calendar so nothing can interfere with your plans to attend. I've heard a lot of excuses and reasons why people missed it, and the main reason is because they waited and didn't get around to it, only to forget until it was too late. I paid for my own entry over a month ago, and know I'll be there. Same with MACNA each year, I pay a year in advance. And I never miss it.
