I normally want event approaches which are unique and out of the box. I think that Youtube is generally a very good source for such ideas. All you need to do is go to Youtube and do a search for "birthday party tips" and you can find many hours worth of movies with many fabulous ideas. The problem is, who has time to view them all? Thus I am on a constant quest to put together some details so as to save me and hopefully others some time.
Here is an awesome video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
I hope you find a number of good tips for your next gathering on Youtube!
