I think it's a law that all beach resorts play Bob Marley! They play him in Aruba all the time, even though reggae music never made it as far south as Aruba, and their native music is more Calypso-oriented. Demographics might change in the future, but I don't see a tremendous lot of salsa/latin penetration in the panhandle area - I think its going be more the Southern Rock/Blues/Country thing - which does have a sub-genre of gulf coast beach music. I'm not too familiar, but I heard a few band play.
And we haven't even brought up Zydeco.
I was so sure that the Tucker family would be into that, I had Elaine hire a Zydeco band for TnT's wedding reception in a story.
