@Anthony1325 Well, a wedding is definitely an event, but obviously a wedding with a dozen people isn't the same sort of event as a wedding for 100.
If you are referring to the Airbnb party and event ban, of course that is designed to crack down on those situations where guests lie about their intentions, throw a wild party, trash the house, infuriate the neighbors, and the police need to be called. It isn't designed to crack down on a civilized family dinner in celebration of your wedding.
Hosts now need to eliminate any wording that would indicate they are open to hosting events. But that doesn't mean you can't look for a large listing that would accommodate your group, and send the host an inquiry message outlining what you would like to do and seeing who might be open to it. A dozen people out in the yard witnessing two taking wedding vows isn't anymore disruptive than a dozen people out in the yard playing croquet.
That said, some hosts have experienced wedding parties to involve far more people showing up than were accounted for on the booking. Hairdressers, photographers, etc, etc. So that's not okay.
Also, your brand new profile, with a grey silouette as a profile photo, zero profile write up, no verified ID, no phone number and no reviews isn't a good portent for being accepted for this type of booking. A host might be open to a booking like this for a guest with a history of great reviews, but as you might imagine, would be likely to decline a brand new Airbnb guest.
Hosts and guests are total online strangers to each other, and while the type of wedding you say you would have may be exactly that, a host would have to be operating on blind faith. A dozen people on a booking which was a misrepresentation of intent, are perfectly capable of trashing a house and most hosts aren't willing to take that risk.
