"First of all, here’s what to say when guests ask what they can bring: 3 bags of ice. 2 to go in the bucket with the drinks, 1 to go in a cooler for other bevs. Chips! Tell them to go wild and bring their faves.  Fruit plate! For the kids. And the fruit-loving adults! Tequila. Add it to the jargaritas at the last minute — you can prep everything else ahead of time. Wine, beer, juice boxes, etc. for people who don’t drink margs. Vanilla ice cream — the good stuff!"
