I typically search for party tips which are unique and out of the box. I find that Youtube is normally a good source for these sorts of tips. All you need to do is head to Youtube and do a search for "party ideas" and you will find hours and hours worth of clips with lots of very good advices. The trouble is, who exactly has the amount of time to watch them all? Thus I am on a constant quest to compile some details in order to save me and also hopefully other people some time.
Here is an awesome video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
I hope you find a number of good tips for your next event on Youtube!
