FI and I are having a holiday party at our house tomorrow. We have a finished basement, but it is going to be "off limits" because it's a total wreck down there (in the middle of a flooring project right now.) There is no door that can be closed; the kitchen leads right into a few steps down to a side door, and then the steps turn and head to the basement.
How should I make it known that people shouldn't go down there? A few people who will be attending have been to other parties where we did use the basement, but most have either never been to the house before or haven't been down there. (We eventually plan to put our bar station down there, but for now we pretty much only entertain on the main floor unless it's a massive party where space is an issue.)
