Marathon Key Fishing Q's

[abc_123]

Planning a familly vacation. Still working out the details but looking at Marathon Key in mid April. Going to do some beach time for sure, trip to Key West to say we've been there. However when surfing the net looking at things to do, my wife immediately zeroed in on the fishing and is 100% geeked to do a fishing charter....

Looking at 3/4 day. Fish species immeterial.

Suggestions? / Recomendations?

Thanks!
