AITA for canceling a guy’s Airbnb booking after finding out he was trying to host his wedding at our house without permission?

So my parents recently bought a house. Before the sale, the previous owners had some Airbnb bookings lined up, but they canceled them once the house sold. My parents were told they could let those people rebook at a discounted rate if they wanted to.

One guy rebooked for a weekend in July. Everything seemed fine. Booked for 8 people, no big deal.

Fast forward to a few weeks ago, and the guy messages my mom asking, “Hey, can we park a truck with a pizza maker in the driveway?” which was already a bit odd. She asked him to elaborate, and he says they’re having “a few” people over for a welcome dinner and hired a company to come make pizzas.

So my mom goes, “Okay, how many people are we talking?”

This man says: "100–120 people."

Like... bro.

For context, where we live, you need special permits to hold events like that, especially at a private residence. This is very much considered an event. So my mom tells him she’s not okay with that, since he booked for only 8 people and clearly never mentioned throwing a whole party.

And then this dude has the audacity to say, “Well, we already told everyone where to go and what time and everything. Can you give me a discount for the inconvenience?”

Reminder: he’s already staying at a discounted rate.

My mom, obviously suspicious at this point, starts digging a bit and finds their wedding website. Turns out they’re getting married that weekend. She’s convinced they were planning to have the actual wedding at the house without ever mentioning it.

So she canceled his reservation on the spot.

Now he’s mad, leaving angry messages, and a few family members are saying she should’ve just let it slide or tried to work something out since it was a “special occasion.”

But like… who tries to sneak a wedding onto someone’s property like that?
