we stayed at place in Key Largo for our honeymoon. It was called Sunset Cover Beach Resort. It was the same price as renting a hotel room only they were small apartments some with a small beach just outside your door others had adjoining apartments. Had a boat dock free of use. It was really nice and quiet. we went at the end of October and it wasn't busy but it is a small place so i'd recommend making reservations.
here's a picture looking out our front door apartment.
