I love diving Key Largo. I went with "Its a Dive" for most of my diving but I also went with Amy Slates as well as her ex’s boat Capt. Slate. They are are pro’s at their job!What is great about It’s a Dive is that they are in charge of all the water sports and activities at the Key Largo Marriott.( I think around mile marker 110?) Almost every place is good and everyone has their favorite. I found that by calling the places from home and talking to them is the best way to choose. Tell them what you want to do and most will do what they can to help you achieve your diving goals and dreams. The more professional on the phone, the more professional the trips are as well as the dive shops
