key west is fun and wild and a great time, but 100 miles north is where you want to dive...key largo. cannt tell you much about kw except where to play and go silly and eat and drink well. KL is the best diving in the US and one of the best in the world. Have a great time and go to the hogs breath and jimmy buffets placeand call your hotel or call a shop in kl. They will advise you well
