I often seek out party ideas which are unconventional and out of the box. I think that Youtube is generally a very good resource for these types of ideas. All you will have to do is head to Youtube and do a search for "party suggestions" and you will see many hours worth of videos clips with numerous wonderful advices. The issue is, who has enough time to see them all? So I am on a constant mission to collect some details to save me and perhaps others some time.
