<human>: I am a senior in Washington, and my three roommates and I decided to throw a Christmas/end of quarter party. I have hosted parties before but with a max number of 15 people. I have invited over 60 with an open invitation to friends of friends. We have a moderately sized house with a large living room and large kitchen. I want it to go well, people are travelling across the state to attend and I don't want to dissapoint. Is beer pong necessary? Loud music? I want to decorate extensively and include my guests in fun things like decorating cookies and drunkly making snowflakes. I have a 30+ year old seemingly working keg without a tap, and it has a mystery liquid in it, can I use the keg? Any advice will help.

Can you provide a brief overview of the text?
<bot>: Any advice on throwing parties, keeping them fun, keeping them in control, and preparation/clean up is needed.
