We stayed on Marco Island in 1998, I wouldnt have said it was particularly up market. We had a villa on a waterway in the middle of a housing estate. The restaurants we found were ok but nothing to write home about, the beach was lovely other than that and the shops there wasnt a lot to do. Our kids were very young when we went, maybe they would enjoy it more now.It seemed geared up to the snowbirds when we went (February).
