I was in Cuba when this new law came into effect. The first few days I was there, a young Cuban lady was at the resort with a tourist. She wore a different colour bracelet and had to leave at 6pm. Within 2 days of the announcement, she was wearing the same colour band as all the other guests, and could stay overnight. She was a nice girl, and quite polite.
I'm not judging by the way...just stating what happened a week ago in Santa Lucia.
