13th Birthday Ideas

I am having my 13th birthday. I went on a website that said a few ideas and i found one that is really cool. You invite girls over and get makeup and face masks and spa food and nail stuff and you all do makeovers on eachother. Im not sure if my friends will like this and i dont want to just have a sleepover, i want something to do before too. I have tried pools to hire but they are too expensive. Does anyone have any ideas?
