Don't encourage or force guests to drink alcohol. Remember to designate before you celebrate. Arrange a designated driver for those who are drinking alcohol. Never serve alcohol to people under 21. If preparing an alcoholic punch, use a non-carbonated base such as fruit juice.
Alcohol is absorbed into the blood stream faster when it has a carbonated base.
Close your bar 90 minutes before your party is over and serve a great dessert treat and coffee, tea or soft drinks. When inviting guests who are known to drink to excess, tell them that drinking and driving is unacceptable at your party. Get their agreement to find alternate modes of transportation. Activities and entertainment should be scheduled to keep the focus on celebrating a special occasion not drinking. Companies holding office parties should consider arranging for discounted or complimentary rooms when a party is held at a hotel so employees won't drive home impaired.
