Cozumel with my wife in Feb.! Love it. Try 'Dive Cozumel,Costa Mayan Charters.' The operator is DIR,iantd,padi+ and will tailor the dive to your liking. He goes places others won't but will be glad to visit the regular dive spots. We did Barracuda (fast current) and had a flight of eagle rays pass overhead! We were at 70+' on the edge of a blue/black dropoff.
