I usually seek out party approaches which are out of the ordinary and out of the box. I think that Youtube is normally a great resource of these sorts of tips. All you have to do is go to Youtube and do a search for "event ideas" and you can see hours worth of videos clips with many different fabulous suggestions. The problem is, who has the time to see them all? Thus I am on a constant quest to put together some notes to save me and 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 some good tips for your next event on Youtube!
