A Mariachi for Your Reception
I love the traditional mariachi music and I especially enjoy quinceaneras where the guests are serenaded by a mariachi band as they eat. You can select a mariachi with other forms of entertainment, just be sure that everyone is very clear about when and where they are to perform so that they don't compete against each other.
For example, you might choose to have mariachis playing outside the reception location as the guests drive up. Once they walk into the reception hall, the guests may be greeted by the beautiful sounds of a string quartet.
And for my readers who are parents and padrinos, don't forget to make arrangements for a serenade of the quinceanera with Las Mananitas on the morning of the quinceanera, or the night before.
