So a Halloween party is happening whether everyone wants it to or not. We've had a ton of new arrivals or a lot of us have turned into recluses who stay inside and binge watch Netflix. What better way to meet everyone else or get out of the slump we've fallen into than with a party?

Before I begin scouting out a venue and then decorating it... are there any hard "no's" here about certain things usually associated with Halloween?
