Do warn your neighbors before the party of extra cars parking in the neighborhood.
Don't let your guests block neighbors' driveways, or trespass on private property.
Do make sure your house numbers are visible and lit after dark. Consider balloon markers or cardboard arrows if your house is difficult to find.
Don't forget to light the walkway with votive candles, paper luminaries (bags with decorative holes), or even a few giant garden candles.
Do specify on the invitations whether or not children are welcome at the party.
Don't forget to provide a sitter for your own children, or plan alternate activities to keep them busy during the party.
Do specify a dress code for your guests.
Don't forget to get dressed up yourself.
Do use familiar landmarks (i.e. a restaurant) as reference points in your directions, especially for night events when street signs can be difficult to see.
Don't forget special instructions for secured building entrances, and directions once your guests are inside, if you live in a large building.
Do clean the areas where your guests will be socializing.
Don't waste your energy cleaning the entire house.
Do consider getting help with cleaning and set-up the day of the party. Hire a teen, cajole a friend, or rope in a family member.
Don't try to do it all yourself, unless it's a very small gathering. The process is half the work and twice the fun when shared.
Do make sure you have enough serving accessories (plates, forks, spoons, etc.) on hand.
Don't spend a lot of money on expensive, posh-looking plates. Use paper products instead!
Do use indirect spotlights, twinkle lights, lamps and candles to create soft lighting that would make anyone look good.
Don't be tempted to leave your overhead lights on (except maybe in the kitchen). It often reminds people of being at work.
Do make your pets comfortable away from the main party area, or ask an uninvolved friend to care for them.
Don't assume that your guests love animals as much as you do. Many people are allergic to cats, and some are frightened by boisterous, jumping dogs.
Do make a plan for guest coats/boots. Clear your own things from the coat closet for the night.
Don't forget to light a scented candle in your bathroom, and leave the door ajar so the room is easy to find.
Do create a realistic budget and stick to it.
Don't forget to budget for unexpected surprises.
