How many drinks...

That depends on your group... but generally for 150 people I would get a 12 pack of diet, a 12 pack of regular and a 12 pack of a sprite or some other flavor. It'll probably be overkill, but you can always take home the leftover. If you have a lot of kids, get more... but if it's mostly adults who drink then it should be fine.

We went through 250 cans with 120 people, but had no alcohol. We did have water, tea, lemonade, and coffee.

On the average, expect guests to drink 2 drinks or servings of a nonalcoholic beverage the first hour and 1 each hour thereafter. Remember, people drink more when the weather is warm.

If you plan to serve bar drinks, you should allow 1 1/2 ounces of liquor for each drink. That means you'll get about 16 drinks from each 750-milliliter bottle (fifth) of liquor. Allow about a quart of mixer -- carbonated water, tonic water, or ginger ale -- for every 3 persons.

When serving wine, plan on one 750-milliliter bottle for every two guests (one bottle for every 3 to 4 guests if the wine will be served only during a meal). If you prefer to buy the large 1.5-liter bottle of wine, it will serve 4 guests (6 to 8 guests if served only during a meal).

When ordering beer for a party, allow about 12 ounces per guest for every half hour to hour. For a large crowd, you might want to buy a keg.

Thank you all for the advice
