Take about 8 guests to a movie in the mall.  Afterwards divide everybody into 2 teams.  Give each team a list of tasks to do. (Things like, What is the flavor for the day in The Ice Cream Shop? and How many mannequins are there in the store 5'7'9'?)  The trick is BE CREATIVE! Tell everyone to meet at back at the movies at a certain time.  The team that answers the most questions correctly wins! Give the winning team a small fun prize like a keychain or stationary. I did this for my 13th party, instead of a boy/girl dance!  Have fun!
