I oftentimes look for event approaches that are out of the ordinary and out of the box. I think that Youtube is truly a good resource for these types of ideas. All you will have to do is go to Youtube and perform a search for "party suggestions" and you are going to see several hours worth of video clips with a lot of fabulous advices. The problem is, who exactly has the time to watch them all? So I am on a constant quest to put together some details to save me and also perhaps others some time.
Here is a great video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
