ORLANDO, Fla. — You’ll notice a lot more traffic near the Orange County Convention Center this weekend as more than 100,000 people converge for MegaCon Orlando.

  • MegaCon Orlando this weekend at convention center
  • More than 100,000 people expected
  • Check it out: MegaCon Orlando

It’s one of the largest fan conventions in the Southeast.

“These are my people, this is where I come to geek out,” said Kaitlynn Calsam, who has been attending MegaCon for more than a decade.

This year's event is highlighted with several cast reunions, from "Boy Meets World" and "Smallville" to "The Goonies" and "Back to the Future."

Many are excited to see Marty McFly and Doc Brown together again.

“It’s really electric when they take to the stage together and share those stories that fit into that iconic series for us,” said Andrew Moyes, Vice President Fan Expo HQ.

MegaCon is a chance for fans of everything, from comics and TV shows to movies and video games, to celebrate, even dress up.

“It’s just a sense of community to find other people that are into the things that you are into,” said Kendra Novelli. “And it’s sometimes really hard in a big city like Orlando to find others, so this is a chance where we all get to meet up and get to know each other.”

Here are other things you need to know about MegaCon:

  1. Be hug-friendly. Cosplayer Chelsea Guy, of Davenport, strategically chose not to wear her Wonder Woman costume on the day she’s meeting Stephen Amell (Green Arrow)
  2. This is the ultimate judgement-free zone: "It doesn't matter what you look like, what you fit, how much money you spent."
  3. Stalk the stars. Their “green rooms” aren’t all bumped up against the celebrity signing areas, meaning some celebs have to walk across the “common area” to get to their booths. So look up from that screen once in a while. You never know who might be in front of you.

MegaCon continues from 10 a.m. to 7 p.m. Saturday and then 10 a.m. to 5 p.m. on Sunday at the Orange County Convention Center.
