Can I have a Quinceanera without a court?

Yeah it is. My 15s was just my sister and I and our guys. The court just represents the fifteen years of your life. Its suppose to be that you get like a little kid for year one, a little older (5) for year two, (three and four), five for five, six for six, and so on. Some people just get fifteen (more or less) good looking people. You do what you feel you would want to remember for the rest of your life.
