Hi,
We had stayed at the El Cozumelano 3 yrs in a row the hotel is very nice food was great I did dive with Scuba du .on site the last time I was there, they are a good operator but there boats are very slow and if your picked up at the hotel expect to spend the better part of the day in the boat for just 2 dives. I like Dive with Martin its a taxie ride but there boats are the fastest. This year we stayed at the Park Royal it was only a one block walk to the dive shop. I’m sure you will be happy with El Cozumelano we were it was just a long taxie ride every day to the dive operator I like best. Enjoy your trip and dive safe.
Joe
