...there many still be some restrictions in place, though they might not be enforced as they are going away soon anyway.
Wrong, and wrong again. There ARE still restrictions in place, and when or if they will go away is completely up in the air.
We are going to open an embassy in Cuba, and allow them to have one here. The current administration has basically said that they are not going to enforce the laws concerning visits to Cuba, but of course that could change completely with the next administration.
As of now, none of the laws concerning visiting Cuba have changed, and Congress has given no indication at all that they intend to ever change them.
...although scheduled flights and ferries are already being arranged.
Scheduled flights have been happening for years now. Nothing at all new there. The only thing new is the talk of possible ferry service. At this point it is only talk, though. The administration has not issued any details on how ferry service would be authorized, they have only said that they would consider it. I would hardly call that "already being arranged."
Bottom line is that very little has changed at this point. Yes, changes are in the wind, and more is very likely to come (I certainly hope so). For now, though, it is still illegal for an American to go to Cuba as a tourist.
The odds of getting caught are even less now than they were before, and they weren't all that great before. So it is probably fairly safe to go. But if you do, and if you are the one in a million who does get caught, don't expect me (or anyone else--most especially anyone who tells you that it is okay to go) to contribute to your legal expenses, or to the payment of your fine. You're on your own.
