The Penny Arcade Expo and its spinoff events have grown in popularity over the last several years, leading to near-instant registration sell-outs. Three-day passes for this year's PAX Prime also sold out less than an hour after becoming available in April.
As of this writing, passes for PAX East's Friday and Sunday showings are still available for purchase. Hotel reservations are available here. PAX East will take place in Boston from April 11 through 13, 2014.
