We are going to spend a week in Cozumel this month. We are certified but have no experience diving. I have learned that Coz is not recommended for beginners, but we would like to give it a try. We would appreciate any suggestions for how to get some experience. Where could we go that isn't too challenging and which dive operators would be the best match for us? We don't want to slow anyone else down - but we don't want to get too far out of our comfort zone either! Thanks in advance for any advice.
