I routinely seek out party tips which are unconventional and out of the box. I think that Youtube is certainly a terrific resource for these ideas. All you have to do is head to Youtube and perform a search for "event tips" and you can find many hours worth of videos with many different exceptional advices. The problem is, who exactly has the amount of time to see them all? Thus I am on a regular mission to compile some notes to save me and also hopefully other people some time.
