I just came back from Key Largo. While there I stayed at the Holiday Inn. Based on recommendations from various members of this forum I dove with Conch Republic Divers and Blue Water Divers. While I definitely enjoyed my dives with Conch Republic, I really enjoyed my Blue Water experience. It wasn't just the incredible convenience of walking from my room to the boat. It was also the fact that Brent and Glen run a really good operation. Fewer divers on a boat means more personalized service is possible. I'm not sure when I'll be getting back to Key Largo; but if and when I do I'll be sure to try to dive with Blue Water Divers as often as possible. (Also, it's really good to know that if Blue Water is booked up, I'll still be able to gets some great diving in with Conch Republic.)
Peace,
Dave
