It's a confusing development. I'm not hearing any change in the rules over who is actually allowed to travel to Cuba and the restriction on them spending money there. That is what will really need to change, to open up the country to cruisers. It does look like it's heading that way.
On the other hand, Cuba has never restricted access to US citizens. They do, however, have significant restrictions on the mobility of all tourists within their country and I don't expect that to change at all. IIRC you have to notify the Cuban government, every time you lift the anchor and move.
Exactly. Regardless of how the rules change, it looks like Cuba will still be a totalitarian dictatorship for now. That's probably going to change when Raul and Fidel are dead, and not one second before, regardless of what any other country does or doesn't do.
But, I've been a Cuba a few times (to Gitmo, on business, but you can see how pretty the water is even from there) (and my brother travels to the other side quite frequently on humanitarian missions) and I, too, look forward to the day when Cuba becomes free and a tourist destination. But, I'm not holding my breath. The Castros cant' look at the new overtures from the US as anything but confirmation that they have won this particular cold war. I don't know what their incentive to grant more freedom to the Cuban people would be at this point.
But, if you can put that part of Cuba out of your mind, you can have a good time there. My brother has received permission to go to non-tourist areas on his trips, and he comes back with reports of poverty that are hard to fathom (not even electricity or running water in some of the homes). And, since the US is really the only country not trading with Cuba at present, you know that there is a much deeper problem going on there, than the US embargo.
