You can't have a party about stocking the bar without plenty of
cocktails.
Don't forget to have enough mixers on hand to satisfy drink
requests. If you're not an expert at bartending, consider getting a
bartender for a few hours. A professional will create drinks with ease
and keep everyone happy, and hiring one is quite easy and affordable
(just check out your local Craigslist).
Sweet Dessert Ending:
Place the chocolate, graham crackers and marshmallows out
separately and rent a few small melting pots that guests can use to
assemble their own dessert.
Bake chocolate chip cookies in the oven after dinner and
present a plate of gooey, homemade cookies to your guests, accompanied
by milk poured into shot glasses.
