I commonly seek out party approaches that are unconventional and out of the box. I found that Youtube is definitely a good resource of these types of tips. All you need to do is visit Youtube and perform a search for "event tips" and you can find hours worth of movies with lots of fabulous suggestions. The issue is, who exactly has the amount of time to see them all? Thus I am on a continuous quest to put together some details to save me and hopefully others some time.
