I might be a bit late but as an original offering why not take the makings of your favourite cocktails?
Big bag of crushed ice, limes, lemons, mint, sugar, tequila cahaca, cointreau, white rum, straws, a muddler and a cocktail shaker.
Start with a caipirinha, follow on with a mojito and finish off with a margarita. then go round again.
Works for Mrs BigJohn.
