This birthday idea is a Luau Campout I had for my 13th birthday. I had everyone sleep over in 3 12 person tents (I didn't have that many people LOL) set around a campfire like camp. My parents and some other trusted adults slept in one than me and my other friends in the other. Anyways, enjoy! Invitations: Bright colours are really good or black font on coloured paper looks great also; eg. red, orange, yellow, green and blue. Hibiscuses should be the main focus of the invitation and are easy to whip up on Word. I bought a heap of plastic hibiscus from the dollar store and attached the invitations to them and gave one to every guest Decorations I bought things off eBay such as blowup palms tree, honeycomb based pineapples and fish as well as streamers and helium filled balloons in light blue, green and pink. I got tiki torches that lit the way from my back door to outside when it got dark and had tents around a fire pit Activites and Games I held the party at about 3pm so it was the perfect time to do water activites without getting sunburnt. I bought 2 cheap blowup pools and filled them with water for the guests to relax on as well as 3 slip n slides (I had a lot of guests). When it got dark we played capture the flag and spotlight tag then roasted marshmellows on the fire Costumes Everyone wore theire swimmers and hula skirts and got handed a lei (which I bought on eBay) on the way in  Party Snacks I had typical party food with a barbecue for dinner. We had a buffet with a large fruit platter, garden salad, caesar salad, cubes of steak on toothpicks wrapped in bacon, cabonossi and pineapple toothpick skewer, kebabs, sausages and make your own burger ingradients  Cake I iced a plain sponge with orange icing and piped pink rosettes around the edge. The fancy fondant tricks were to hard for me so I kept a couple of the dollar store hibiscusesand aranged them on the centre  Favors I had the leis given to them at the start of the party and had mainly fruit flavoured lollies in the party bags. The party bag was a little hessian bag tied together with a little rubber with a flower from a lei I pulled apart
