3.You need more ice than you think. Make sure you over buy ice. If you have an ice maker attached to you fridge, it will not hold or make enough for your guests. You will need ice to keep drinks in the cooler cold and ice for people to put in their drinks if they choose.
4. Stock Your Bar.
•For the wine drinkers, have one bottle for every two people, assuming five servings per bottle.
•For the beer drinkers, have one six-pack for every two people, assuming 12 oz. servings.
•Get one or two liquors that can be made into a variety of cocktails (probably vodka, rum, gin, scotch, bourbon, blended whiskey, or tequila)
•Don't forget mixers and garnishes, including orange juice, soda, tonic, ginger ale, cola, grenadine, tomato juice, Tabasco, lemons, limes, horseradish, and Worcestershire sauce. The most important mixer, however, is seltzer (club soda - if you must).
5. Prepare The Menu. Aim for variety (meat, vegetarian, hot, cold, spicy, and sweet). If you're not serving dinner, estimate 6 bites per person, but remember that it's better to have too much food than not enough.6. Buy a fabulous outfit. Focus on the atmosphere of your party. Will you be mingling the whole time? Will you be busy refilling drinks and food? Will you have games or other activities such as a bon fire? These are things to keep in mind when dressing for your event.
7. Offer water and coffee towards the end of the night. Coffee and water do not help increase sobriety but they help with the next day hangover. Keep the number of a local taxi service handy for those guests lacking a designated driver.
