I usually hunt for party tips that are unconventional and out of the box. I think that Youtube is undoubtedly a very good resource of these kinds of tips. All you have to do is head to Youtube and do a search for "event suggestions" and you are going to find hours worth of clips with numerous fantastic ideas. The trouble is, who has enough time to see them all? So I am on a continuous quest to compile some details so as to save me and hopefully others some time.
