These days, there’s far more to being a fan than just enjoying your favorite movie franchise, TV show or book series. Fandom is an immersive experience that allows characters and stories to live far beyond their original incarnations.

J.K. Rowling’s Harry Potter novels constitute one of the largest fandoms worldwide, with conventions, theme parks and even cruises bringing fans of the boy wizard together. Given that Las Vegas is one of the most popular convention cities in the world, it makes sense that Potter gatherings would make their way here.

PotterCon’s PotterParty is a traveling get-together strictly for adult Potter fans, who can cut loose without worrying about impressionable young readers. Activities at PotterParty include costume contests, trivia, games and more, with vendors setting up to offer a curated selection of Potter merchandise.

Instead of a convention center, PotterParty takes place in a concert venue, with plenty of adult beverages and raucous interactions. It’s the best of fan culture combined with the fun and spontaneity of a night out in Vegas.
