Planning to dive with Horizon Divers in Key Largo in August. Curious to know if anyone has experience with this company. They were recommended to me by my LDS. I have reserved spots for me and my son for 4 days of diving. The woman on the phone was VERY nice, VERY patient, and was able to answer all of my questions. I'm sure anyone that has dived in KL will have their own recommendation for any of a dozen (or more) shops. I'm particularly interested to know about Horizon. Thanks much.
