Disco Themed Bachlorette Party

I am planning my best friend`s bachlorette party. I really want this to be a night she will never forgot. Plus I want it to be something original and new for all of us girls. Jodie loves disco music. I think she would love a disco themed bachlorette party. Does anyone have any suggestions from cocktails to dress to invitiations to the place to go? We live about 20 minutes outside Manhattan. We`ve both been to the PolyEsthers. I don`t think she would like her party there. It seems she might be one of many brides if we go there. Any ideas would be greatly appreciated.
