I commonly search for event ideas which are unconventional and out of the box. I learned that Youtube is usually a very good source for this kind of tips. All you have to do is go to Youtube and perform a search for "party tips" and you are going to see hours and hours worth of videos with many different great points. The issue is, who exactly has time to watch them all? Thus I am on a continuous quest to gather some notes in order to save me and also hopefully others some time.
Here is a great video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
Hope you find some great tips for your next gathering on Youtube!
