What It Feels Like to Be There

“We came to Mega Fun Halloween last year and honestly? Best decision. My two were in costume, dancing, bouncing and laughing all day. And I got to sit down with a coffee. Heaven.”Claire, mum of two

“I was expecting chaos… but it was so well-run. From the inflatables to the spooky disco, it felt like Halloween done right. No queues, no chasing. Just pure fun.”Matt, dad of three

👻 What the Day Actually Feels Like

You grab a hot drink and sit back.

They run off in costume to bounce, race, and high-five tiny vampires and mini witches.

The disco kicks in. They’re spinning, laughing, showing off their best zombie moves.

You’re not checking your watch. You’re actually enjoying a Halloween event.

And on the drive home?

They’re quiet. The good kind. The tired, happy kind.

“I started Mega Fun Day because I was sick of spending a fortune just to be stressed the whole time. Everything was either too loud, too busy, or just not built for real families. I wanted something simple. A day where kids could be kids and parents could actually breathe. That’s what Mega Fun Day is.”Marky T, Founder & Dad of 2

Let’s Clear It Up

Is it crowded?


Nope. We cap numbers to keep it calm. More play, less waiting.
