General Registration* opens at 12 Noon Pacific Time on Monday, May 7, 2012. An $85 deposit gets you signed up and assures you the best seating preference available. Your deposit is fully refundable through December 31, 2012. So you really have nothing to lose, except guaranteed seats at a convention that sells out regularly.
*Advanced registration opens for MAGIC Live 2011 alumni on Monday, April 30, 2012.
