I usually want party tips that are unusual and out of the box. I think that Youtube is certainly a very good resource for such tips. All you will have to do is visit Youtube and perform a search for "party ideas" and you are going to find hours worth of video recordings with a large number of awesome tips. The issue is, who has the amount of time to see them all? So I am on a regular quest to compile some notes so as to save me and also hopefully others some time.
Here is an awesome video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
Hope you see a few good tips for your upcoming party on Youtube!
