Party Help

I`m inviting at least 25 people to my party. It`s going to be a hawaiin theme. There is going to be at least 10 guys there and 15 girls. I don`t want to play 7mins in heaven&probably not spin the bottle. We`re going to swim in my pool, and have a bonfire when it gets dark. The people`s ages will be from 10(my brother who has to join) and 15. My biggest crush. I am 13 1/2 yrs old. I want ppl to sleep ova, but i don`t know who.guys are alould to sleep ova but not ova 4. Up to 6 girls are alould to sleep ova. My friends are not mature, and not really into guys yet, but i am. They might think it`s weird that i have Co-ed sleep ovas. Also i need some party game ideas, fun ones, but not much with kissing. But with hugging though. P.S. I have done things with guys though... If u know what i mean. Please help me!!!!!!! thx bye
