papa58- I have never been to ocean beach club. I normally just go out to the taxi area, they have a sign they has the fares to several beach clubs. You can get good deals out there. Beware to the stands inside the port area that have guys selling beach breaks. They are way overpriced and one sells access to a hotel that is right there next to the port...
We have done a couple- The Hotel Cozumel Carib" is good, the Money Bar (might be the Dollar Bar) is okay but does not have a big beach. Then the last time we went we ended up at a place just south of Chankanaab... it may have been Playa Maya but Playa Del Sol sounds familiar too. They had a great set up. Food, showers, beach chairs, sea kayaks, snorkeling gear, etc..
But most of the taxis will get you to a good beach for a better price than the hawkers inside the port area.
