STARTING AND FINISHING TIMES
To ensure prompt arrival at your party, ask the parents to arrive with their children at e.g. 2.55 p.m. rather than informing them the party is between 3.00 p.m. - 5.00 p.m.
If you would rather not have a house full of adults, looking around eagerly for the wine bottle at the conclusion of the party Try this:
Allow a little extra time at the end of the games, etc., so you are completely finished about 5 minutes before the stated time on the invitation. This will allow you to have their little darlings waiting for them on the front door step, with party bag in hand when they arrive.
