I normally try to find event ideas that are unconventional and out of the box. I found that Youtube is a good source of these sorts of tips. All you will have to do is head to Youtube and do a search for "event suggestions" and you will see hours worth of videos clips with a lot of exceptional ideas. The problem is, who exactly has enough time to see them all? Thus I am on a regular quest to compile some details to save me and perhaps others some time.
Here is a great video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
I hope you see some great tips for your upcoming occasion on Youtube!
