KY granpa's first visit to Perdido Key

Will be there next week with my 4 1/2 yr old grandson and hope to do a little fishing. Normally we go near Venice and have a blast fishing on the jetty for mangrove snapper. Any similar fishing in the Perdido Key area? The little guy is happy to catch anything from bluegill to snapper. I thought about taking him on a group charter but his attention span is like any other 4 yr old he's only good for a couple of hrs then likes to head to the pool. Any advice/suggestions greatly appreciated.
