With the Caribbean’s largest island opening up to travelers from the United States, Americans are flooding in. Glitches with reservations and transport still occur, however, so it’s easiest to take an organized trip. Independent travelers can stay in Airbnb-style accommodations, called casas particulares, via trips they book on their own. Independent travel likewise allows you to meet locals, dance ’til dawn at music clubs and sample — and bring home — Cuban cigars. U.S. airlines fly in and will arrange visas. Note, though, that pure tourism is still illegal. Your trip must officially be for “people-to-people” interaction or some other authorized purpose.
