I often look for event tips that are unconventional and out of the box. I learned that Youtube is truly a great source for these kinds of ideas. All you have to do is check out Youtube and do a search for "party ideas" and you will find hours and hours worth of movies with a lot of wonderful advices. The problem is, who exactly has time to view them all? Thus I am on a continuous mission to collect some notes so as 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
I hope you find a number of good ideas for your upcoming event on Youtube!
