Sweet 16

Okay guys so I really need your opinion on this. I want to have a sweet 16 and I was planning to already. I have my dress already to. So today we wen to reserve the room and everything. Everything is going to be around $2,000. Now I am thinking of not having one and just get a new phone instead becuse right now I have the 5s. But at the same time I want to have a sweet 16 cus it only happens once in your like. I don't know what I should do now.
