.. without an OFAC permit.
You'll notice that the travel ban is on Americans only.. not Cuban-Americans nor Cuban immigrant resident aliens.

On March 24, 2003, the Treasury Department’s Office of Foreign Assets Control (OFAC) announced amended regulations on travel to Cuba from the U.S. Though OFAC accepted comments on the regulations until May 23, 2003, there is no formal review process and the regulations go into effect with no real congressional oversight.
People to people travel category eliminated
The new regulations eliminate non-degree related educational travel to Cuba: the 2nd largest license category of travelers, which combined non-credit educational activities with people-to-people contacts. People-to-people travel was licensed by the previous administration, with the belief that such contacts between the two nations would promote American democratic ideals; this travel policy toward Cuba was modeled after the successful exchanges that took place between the former Soviet Bloc and the United States years ago.
* Specifically, the new regulations abolish section 515.565 (b)(2) of OFAC’s Cuban Assets and Control Regulations. Effective March 23rd, “…specific licenses will no longer be granted to sponsor people-to-people educational exchanges to take individuals under their auspices on educational trips to Cuba unrelated to academic coursework.” (OFAC Report for Congress, updated April 22, 2003) The new OFAC regulations will be a major setback for universities, non-profit orgs, professional associations, museums, religious groups, American businesses, continuing education programs, etc.
Cuban American restrictions eased
The new regulations eased restrictions on the largest category of travelers: Cuban Americans. The definition of a close relative was broadened and the amount of cash remittances a Cuban American may carry to Cuba rose to from $300 to $3,000. The per diem spending limit for Cuban Americans was lifted entirely. Effectively, OFAC has eased conditions under which Cuban-Americans may travel and has narrowed them for most others. This leniency arises from the fact that a majority of Cuban Americans now support lifting the travel ban. Still, many Cuban Americans complain that getting permission for more than one visit--even in extreme cases like death in the family--is too cumbersome and cruel; often these visitors return home illegally, through third countries.
