We recently took the other Carnival ship out of Tampa for the 4-day cruise to Cozumel. The ship does departure day, then one day at sea, one full day at Cozumel, and then another day at sea, and then arrival in the morning.
We booked our dives through the boat. The price was reasonable and the service was good and the diving was great.
You can book them yourselves if you want to, but why bother?
