On a Friday morning in February, the lobby is quiet, its palm-filled courtyard unoccupied, belying activity in parts unseen, including an emergency room and a maternity ward.

Cancun’s beaches draw in visitors by the millions each year, while Galenia attracts a distinctive kind of tourist: those seeking health treatments not sanctioned by the U.S. and governments elsewhere.
