I normally seek out party ideas that are unconventional and out of the box. I think that Youtube is certainly a terrific resource for these types of ideas. All you need to do is go to Youtube and do a search for "party suggestions" and you can find hours worth of clips with many exceptional suggestions. The trouble is, who exactly has enough time to see them all? Thus I am on a constant quest to put together some notes so as to save me and also hopefully others some time.
Here is a great video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
I hope you see some great ideas for your upcoming celebration on Youtube!
