I normally hunt for event tips that are unconventional and out of the box. I learned that Youtube is definitely a great source of these kinds of tips. All you will have to do is browse Youtube and perform a search for "party tips" and you can find hours worth of videos with plenty of great tips. The trouble is, who has enough time to see them all? So I am on a constant quest to compile some notes so as to save me and also perhaps other people some time.
