Don't know if this'll work, but I sell UndercoverWear and I'm ALWAYS doing bridal showers. One particular game I find goes down well is 'whats In My Suitcase?' Everyone gets a piece of paper and a pen, and they write down your initials and DH's initials. Then they have 3 minutes to write down what they think you should pack for your honeymoon (or labour bag!), but the items hafta start with one of your initials.

It ALWAYS breaks the ice at my parties!
