Is it rude to have a B.Y.O.B. wedding dance?

we are having our wedding next summer at a lakeside resort, a simple romantic ceremony, a bbq supper, music and outdoor bonfire/dance/party..celebration, to follow. we are trying to keep the wedding as low budget as possible, would it be considered rude to have it bring your own beverages? we would have "beverages" for family, wedding party...and some non-alcoholic beverages available as well, mostly for kids.
