I’ll be with a friend diving the Cenotes on July 4th. We’re going with Carey Dive Center based in Isla Mujeres. You could probably go on that trip with us. You might prefer to go without a guide, in which case, it’s not for you. The rest of the time 7/2-7/8 we’ll be diving in Isla Mujeres, so our paths can’t cross. I dived in Cozumel a few years ago, and it was wonderful.
