"We still have tons of single day passes, but we strongly suggest people buy their passes sooner rather than later," event organizers told us. "Their pace tends to accelerate after we run out of three-day passes."
Another thing to remember is that there were issues with counterfeit badges sold at PAX Prime last year. Fake badges won't get you in the door and, if you get scammed, PAX organizers won't help resolve the problem. So, get those PAX East tickets now for the April 6-8 event.
