I normally try to find event ideas which are unique and out of the box. I find that Youtube is certainly a wonderful resource of these ideas. All you need to do is check out Youtube and do a search for "party tips" and you will see many hours worth of movies with numerous very good ideas. The issue is, who has time to view them all? So I am on a constant mission to put together some notes to save me and perhaps others some time.
Here is a great video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
I hope you see several great ideas for your next occasion on Youtube!
