I frequently want party approaches which are unusual and out of the box. I found that Youtube is certainly a great source of this type of ideas. All you will have to do is go to Youtube and do a search for "party suggestions" and you will find several hours worth of clips with a large number of exceptional ideas. The issue is, who exactly has the amount of time to view them all? Thus I am on a continuous mission to gather some notes in order to save me and also perhaps others some time.
Here is a great video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
I hope you find some great ideas for your next celebration on Youtube!
