alty endeavors ( also contacted Tres And Liquid Blue) The only problem with them is they do the brake on the boat. I would really rather have a beach club with a bathroom etc. for that hour break.
It varies. I dived with them a couple of weeks ago. I doubt that all beach clubs welcome bathroom visitors who seldom spend money, and at times they can't stop as they need the time to change sites. Most divers pee at the Safety Stop, but if you really need a bathroom dump, tell the captain. Talk with the owner if you'd like, Henry. He is a pretty agreeable fellow and available to talk even tho he does have to have assistants answer some emails for the growing business.
We are a family of three, our 10-year-old will be diving with us. we are all new divers, with nine dives each including two ocean dives in Hawaii. The most important thing to us, of course, is safety.
Since this is your first visit, these are my suggestions for Cozumel newbies...
> DAN dive insurance is essential. Explanation available.
> Do not ever rent scooters.
> Get trip insurance with at least $100K medical unless you are totally sure that your home medical insurance will cover you well in Mexico. No one expects issues, but they happen. DAN offers a pretty good deal, but Generali has better rates. Repatriation is included in DAN membership, but also included in most plans.
> Hire private DMs for each newbie or couple the first day, and remind them to explain escaping down currents.
> Everyone buy and carry SMBs and Storm whistles even if using rental gear.
I guess you know to not drink the water and negotiate cab fares before boarding. Use your debit card at BANK OWNED ATMs (not free standing cash machines that are dangerous) to get Pesos as most things are cheaper in the local currency.
