Don’t be goofy, buy your tickets! If you plan to attend Mickey’s Not-So-Scary Halloween Party but haven’t bought your tickets yet, don’t put it off much longer. August 16 is now sold out! While that may seem like a random date, it is the first day when tickets are $109. The first party, August 12, costs $139, which is quite a bit more if you’re buying several tickets. I do think that August 12 will sell out soon. The first date to sell out was Halloween itself.
