I would invite some people over to get ready with, then play music for the guests coming in and have drinks on hand.
Tell the neighbors what will be happening and also don't have the music playing to loud and HAVE FUN!
Maybe start around 5-6? Um play loud music as people come make sure you have more than 3 friends there in the beginning to get things started ummm that's all I can tell ya'
