I regularly hunt for event ideas that are unconventional and out of the box. I learned that Youtube is truly a good resource for this kind of ideas. All you need to do is head to Youtube and perform a search for "party tips" and you can see several hours worth of videos with various wonderful suggestions. The issue is, who has the time to watch them all? Thus I am on a constant mission to put together some details so as to save me and also hopefully other people some time.
Here is a great video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
Hope you see a few good tips for your future event on Youtube!
