DECORATIONS: Hang up yellow, orange, and green streamers all over the place since you can get a huge roll for $0.75 and streamers always dress a place up. Cover the buffet table with a multi-colored tablecloth and then a huge sheet of astro-turf for a Hawaiian feel. You should reserve one brightly lit and especially decorated area or room, cleared of rugs, lamps, breakables, and furniture, for dancing, snacking, and romping. Here is where the girls can work out their energy and make a mess to their hearts content. In the bounce-around room is where the CD player should be so the guests can rock to Linkin Park as well as sway to the Hula! Hang up tropical looking curtains and posters. Make palm trees out of construction paper and stick them to the walls. String up colorful templates and patterns too.  Also keep one off-to-the-side room for calm and quiet. In the middle of the room, make a huge pile of ultra soft pillows mixed in with teddy bears and other bedside companions. This can be the peace-room/snuggle heap for those who want to hit the sack early.
