Hawaiian Beach Bash
You don't need a beach to have a blast of a luau. This party is easily converted from actual island splendor into the confines of your living room. Just be creative with the decor and be sure to have hula music on hand -- the mood will be complete.
Game: Hula Hoop contests. Be creative with your tasks. Mix the traditional "who can hula hoop the longest" with some other goals. Who can sing "Happy Birthday" the longest? Who can recite the alphabet? Be sure to start off the game playing with a hula lesson for those who may not have the hang of it just yet.
Party favor: Leis.
