I live roughly 2000 miles away from anyone I'd celebrate with, but my wife and I live close to my mother in law, meaning that we'll spend the holidays close to home and save for the specific days themselves will have the same or more time to play, but much of my raiding guild will be traveling and as a result raiding will most likely be suspended from mid December on. This wasn't as much of an issue for us last year due to Wrath of the Lich King launching in November... the holiday season was taken up by folks leveling... but this year it looks like five mans will be our major WoW excursions until the new year.
So what about you? Will you be raiding as usual, taking some time off, running heroics, or even levling alts? How will the holidays change how you play WoW?
