Eurovision is the one night a year when maximum effort is not only acceptable but essentially mandatory, so your party should match the energy. Start with a ballot sheet for every guest, and a snack spread loosely themed around the competing countries. Dress code is sequins or go home. Have a signature cocktail, pick your favourites before the voting opens, and prepare to be completely wrong about who wins. Chaotic, communal, and completely unmissable - exactly as intended.
