We're going to Grand Cayman over Thanksgiving. One person has finished PADI course and needs to do certification dives. One inexperienced diver (less than 10 dives). One slightly more experienced diver (less than 100 dives). Would appreciate recommendations on dive operators to handle all three divers. Last trip to Caymans was in 2000 and we dove with Fisheye which apparently isn't there anymore (too bad - we had great experience). We're staying at Treasure Island condos and will have car. One non-diver also going.
