cypress Island

Were trying to put together a trip to Cypress Island within the next month, were thinking two or three days remote camp ..on google earth it looks like a good float with good camping. Has anyone ever did this float ..and if so is there any good fishing in that area   fishing isn't everything but it helps,,,oysters, crabs any info would be helpfull, any one intrested in the trip let us know a small group would be fun...  Jim l
