I'm not sure of the age group of your crowd, but I would say the "punta boys" are definely for a younger crowd. We've heard them, and I'm not sure I'd want them for a wedding party. Our son was married on the island last June, but we just hired someone for the beach ceremony. The suggestions about Will and Dale, or Dennis Wolfe, (he'd be my choice for a mixed crowd, all my kids loved him)are probably a good choice.
One other suggestion: We had a great "rehearsal" party the night before the wedding with a sunset cruise on the Lady Sharon. Rodney will treat you
