Check Cruise Ship Schedules

I look at the cruise port schedule whenever we head to Cozumel. I don't have a choice for vacation time really due to my job and hubby's job so we're stuck with what we get but I check the schedule anyhow. We leave for Coz in a couple weeks. Most days we are on island there will be anywhere between 4-8 ships docked. Hope we can get a taxi to the marina for diving!
