I routinely seek out event tips which are unique and out of the box. I found that Youtube is certainly a wonderful source for such ideas. All you have to do is head to Youtube and do a search for "party suggestions" and you are going to find hours and hours worth of video clips with lots of exceptional tips. The trouble is, who has the amount of time to watch them all? So I am on a regular quest to collect some details so as to save me and also perhaps others some time.
