yes, the cruise ship ops are going to take divers to easier dive sites, so not really the best of Cozumel.... because of the current. Last thing they want is to be chasing divers, who get too high in water column (water moves at different speeds at different levels off the reef... lower is slower). Having been there, doing lots of dives over the past 16 years, I can say I have seen once a year divers suddenly at the surface because they weren't paying attention to the current, or staying close to the reef. They end up getting separated from the rest of group...which is terrifying for the DM as well as the divers. THAT is why they take divers to what they hope will be "easy" Cozumel dive sites.
Current varies day to day, and is affected by moon cycle and weather conditions. No way to know for sure until the DM drops in the water to check it out.
