I typically look out for party approaches that are out of the ordinary and out of the box. I think that Youtube is without a doubt a good source for these sorts of tips. All you have to do is browse Youtube and perform a search for "event ideas" and you can see hours worth of movies with many different very good ideas. The problem is, who has the time to see them all? So I am on a regular quest to put together some details so as to save me and also hopefully others some time.
Here is a great video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
Hope you find some great ideas for your future party on Youtube!
