From The New York Times:
If they cannot go as tourists, put ’em to work.
The New York Philharmonic canceled a trip to Havana last year because the United States government refused to allow its wealthy patrons to go along, saying they would essentially be tourists. That violates sanctions banning most travel to Cuba.
So the Philharmonic quietly resubmitted its application, this time adding a children’s concert and Kidzone beforehand and stating that the patrons would be involved in the activities, officials at the orchestra and in Washington said in recent interviews.
