We stopped off at Anna Marie Island last Sept. We got there about an hour or so before sunset and went to a very secluded beach. It was very pretty. There were no shells to speak of. We were going to stay on AM but since we didn't book ahead, there were no vacancies. We continued south down to Sarasota and stayed there for 2 nights. We continued on next to to Sanibel Island-which we really enjoyed! Tons of shells and the water was lovely to swim/float in.
