Parties and events are banned on Airbnb (unless you are speciality venue, such as a hotel). See: https://news.airbnb.com/airbnb-announces-global-party-ban/
Apart from the potential issues @Gwen386 mentioned, if someone, e.g. a neighbour, reports the party to Airbnb, they will most likely shut instantly suspend your listings and possibly cancel future bookings.
Just don't go there. If a guest asks for this, it's simple. All you have to tell them is that Airbnb prohibits parties and events.
