Luau themed party Help!!! 10 points?!

I'm turning 14 and will be having a luau themed b-day party. So im renting tents, chairs, tables, and i want to rent a water slide. Serve as a treat pinapple, pretzels, marshmellows, fresh fruit, etc. next to a chocolate fountain! (they can dip treats in fountain) Then i already have the glowsticks! And i was thinking of giving out leis (those flower necklaces) as they enter my backyard to my birthday party! And then with christmas lights the ones that are like plain white and then the colorful ones wrapped around my gate in my backyard. Then have like cut-outs or like scene setters of hawii girls in grass skirts. Then Around hang those lanterns from the tents all around. Have like a bubble machine, . . . . to make it look idk . . . i just want the bubble machine:) . . . . . anyway then have beach balls like in random places (on the floor) Then have flowers as the centerpieces with a plate and happy-Birthday-mints as the wrapper (i already bought them) on the bottom. Then im having my home streo <- (sorry idk if i spelled it right) system thing turn the bass all the way up put the volume on high and us that as my music. Have also a hula girl as a pinata, im going to also have a giant balloon of a hula girl saying happy b-day at the entrance (its like 2 1/2 feet tall)
Then i was thinking of having like clear glass plates with water and then a floating lit candle. 2 per table so in the night everything can look lit up!
And send out invitations well i think it will just also be a hula girl on the cover then like the date, time, location, etc, Unless i get a better idea:[
*Oh i forgot and on the cake it will have my picture on it with lots of flowers saying happy b-day!

If you have any more ideas or suggestions please let me know or tell me if i have to change anything or something idk Help! Thank you in advance!

P.S= This will be for 50 people both female and male, all age groups!
