I usually want party ideas which are unique and out of the box. I think that Youtube is normally a very good resource of such ideas. All you have to do is browse through Youtube and perform a search for "event ideas" and you are going to find hours worth of clips with countless good ideas. The trouble is, who has the amount of time to view them all? So I am on a constant mission to put together some details to save me and also hopefully other people some time.
Here is an awesome video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
Hope you see some good ideas for your future celebration on Youtube!
