Passes for Celebration Chicago went on sale Tuesday, and it doesn’t seem like the price increase has had any effect on demand. 5-day passes were sold out by Thursday morning, and 1-day passes for Saturday are 60% sold out..

It took months for those to sell out for Orlando in 2017; 4-days for Anaheim in 2015 sold out just before the con began. At this rate, the Celebration after this one is going to be like SDCC. (AKA: Utterly ridiculous.)
Hotel rooms have also been an issue, but keep checking back. I didn’t get anything Tuesday, but I managed to nab one Wednesday. Good luck!
The con is being held April 11-15, 2019 at Chicago’s McCormick Place.
