The Pier house is good and the Ocean key resort is right across the street, they are both located on Duval st. Lots of places to explore and eat. Lots of bars. they got a good place that makes fudge and ice cream on Duval st. Definitely do a kayak trip good way to see the island i'm sure they have kayak tours . The conch train is a open tour to show you the sites they drive around the island. Fishing is good depends on what kind you would like to do backcountry or offshore sailfishing is red hot right now. Water temp just dropped down to 80 degrees thats still good for diving or snorkeling just pick the right day [calm seas]don't forget the sunset at Mallory Square good drinks and some street performers always fun to watch the sunset in Key West
