So, you're going to supply monetary support to a communist regime?
Some of us have morals that prevent that sort of behavior...

We did two dives there, the worst dives of our Cuba itinerary.  Water was
green.  Fish were gone.  But I bought a T-shirt anyway.

Havana Bay was interesting diving, what I remember of it.  It was in big
seas, I was extremely hungover, and nauseous from both.  That's all I
remember, other than the fact that the water was clear but not warm enough.

My favorite was the shore diving in the Bay of Pigs, then going across the
street to a rustic restaurant for lobster and Cristals, and doing a gear
rinse dive in the cenote behind the restaurant where our guide pointed out a
shell that had been dropped by the Yanqui capitalist pigs during their
failed invasion of the glorious communist republic.  Then he confessed that
it actually landed somewhere else, but they stuck it in the cenote to
impress tourists.  We did a great night dive at the same site.
