I routinely look for event tips that are unique and out of the box. I think that Youtube is truly a terrific resource for this kind of tips. All you will have to do is browse Youtube and do a search for "birthday party tips" and you will see hours and hours worth of movies with numerous fabulous suggestions. The problem is, who exactly has time to see them all? Thus I am on a regular mission to gather some details to save me and also hopefully other people some time.
