Hawaiian Luau (Graduation)?

Question:I am having a graduation party at my house for all my senior friends. I am cleaning out my garage and covering all the walls with blue sheets and fabric. I want to cover the floor with sand but idk how much it is or if my dad approves. I am going to keep the garage doors open (the big ones where the cars come in) and hang paper lanterns in the door ways. I am going to use card board and paint bright signs that say beach this way and stuff like that.. I am also going to make a cardboard surf board with an ocean view on it. I am getting an inflatable palm tree and some flower petals to spread around. I am hoping to get round tables and cover the tops with blue or green table cloths and wrap a grass table skirt around each. For the tops of the tables I want to have either Hawaiian looking flowers or a coconut candle in the center surrounded by seashells. Also on the ceiling I want to have a blue sheer fabric with white Christmas lights. I will probably have a few beach balls laying around. My dad is making me this tiki bar (a cheap one) using plywood for the table top and using bamboo rods to hold up the top. I am planning on covering it the same way I will do the tables with a table cloth and grass skirt and a grass skirt also for the top (roof) of the tiki bar. I was going to make a little area where people could change but I don't know how I could do that. I was going to make it out of fabric but I thought people could easily pull it open so it wouldn’t be too private. Oh yeah I was also going to get a fish net and hang it over the fabric wall and put fish and sea shells in it. Out side I want to have tiki torches, a sign, maybe balloons. We have this huge black tarp that we always use as a slip and slide, I know its kind of juvenile but it's so much fun! I was thinking about renting a volley ball net, but I’m not sure about that yet. I was also going to have music playing in the garage to set a mood. For food I was going to have hot dogs, hamburgers, chips and salsa and drinks with cocktail parasols to serve at the tiki bar. For gift bags I was going to give stuff like seashell necklaces, ocean or coconut scented soaps and sprays, surf board key chains, maybe a cute notebook idk tell me if you have any ideas especially for guys. But yeah that’s about it if you have any ideas please let me know. If u have done a luau tell me how yours went thanks. I am buying my stuff from oriental trading, dollar tree and wall-mart.

Answers:
Its sounds like you have planned a great party theme.

Pineapples make great centerpieces standing alone with some palm frawns laying around. Or you can core them the day of the party and insert tapered candles, plus you can serve the pineapple to your guest or add to the drink carousels. Due a sample test in advance (good pineapple coring is kind of tricky)

Good gifts for guys are Frisbees or squirt guns. (yes, they are juvenile also, but they are fun entertainment.)

One idea is too put the tiki bar in front of the changing area so someone will be around to stand guard.

Enjoy your Graduation party.
