Spa Birthday Party at Home?

I am turning 16 and was brainstorming ideas for my birthday. One of my ideas was to have a spa party where we set up a little area in the master bathroom where we can do each other's nails, do facials, and talk. We will have appetizers and later pizza and cake for dessert. At the end of the party I will hand out party favor bags with body lotions, etc. I like this idea, but think it may seem like a 12 year old birthday party, what do you think.
