I'm having a Halloween party, mid day on a Sunday. Many of the guests will be parents with their kids. So far there will be about 25 adults and 16 kids (around 10 years old). If I had to guess, about 12 of the adults will be drinking alcohol (approximately).
I am planning on Sangria in a punch bowl, plus some white wine and possibly some beer.
In addition to the alcohol, I'm having soda, apple cider, some bottles of non-alcoholic drinks from Trader Joe's and some teas and coffee.
Any suggestions on how to plan when purchasing alcohol for the guests?
