13th Birthday Party Ideas?

I am 12 turning 13 years old in June which is winter. It's always raining here in Australia. I don't own a pool. I want to have a big party, but not too big, with boys and girls. It needs to be nothing too expensive tho 100-200$. I have already done the roller skating, etc. I can't use my garage and I'm not a girly girl. I don't want to do facials and spas because there will be boys there as well. Please is there anyone who can help me?
