23 SEPTEMBER 2015
Emerald City 4 day tickets are gone. VIP packages are still available as of 1:17 pm PST and so are single day and 3 day tickets. Note that ECCC announced Nathan Fillion as a special guest (for both Saturday and Sunday), which might persuade more people to snap up a VIP pass.
Most hotels have availability, but Wednesday night sold out fast at Sheraton, Hilton & Hyatt and Thursday night is already gone at some as well. Please don't wait any longer; get your tickets and hotel room today.
Again for historical context:
ECCC 2014: full passes sold out in 5 months.
ECCC 2015: full passes sold out in 7 weeks.
ECCC 2016: full passes sold out in 50 minutes.
That's Comic Con life right there.
However, it's important to note that anyone can still get in and get a ticket right now. There's no queue; this isn't like SDCC where thousands of people are turned away. Even if you wanted a 4 day ticket, you can still buy single day badges or VIP and get the full experience.
ETA: Celebrity Fast Pass packages have sold out. I'm guessing Special Access will go next. Don't wait any longer.
ETA: Now Special Access is sold out too. 3 day and single day are still available.
