Holy Hell! The Doctor Who Convention is the same weekend as the Star Trek convention and next week the city belongs to the Lord of the Rings fans and the Oscars. You need to get yourself outside just to see wizards, time travelers, Klingons, celebrities and robots and I don't just mean in front of the Mann's Chinese.
Wow, I didn't have time to warn you about this one, but Gallifrey One, the Doctor Who Convention is sold out.
February 15-17, 2013 at the Marriott Los Angeles Airport Hotel
If you already have passes good on you, but if you don't I'm sorry to say your time is up. I'd still look in forums and sites to see outside fan activities.
