It looks like rational minds have decided to return the D23 Magic & Merriment event to the second weekend in December. The earlier D23 calendar had scheduled the holiday event for the crowded third weekend of December, when schools and colleges start their Christmas recess. There is also a choice of dates, so twice as many D23 members can participate. Hopefully, tickets for the 2011 holiday event will be available for two minutes before selling out! LOL
