ITALY-VATICAN-CANONIZATION — **Getty ImagesT**he double canonization of Popes John Paul II and John XXIII on April 24 is bringing travelers to Rome and Vatican City.

On April 27, Pope Francis will host a spiritual doubleheader of sorts in Rome for two of Catholicism's most illustrious leaders: Pope John XXIII and Pope John Paul II. The late popes –- the former who sought to modernize the church through Vatican II, and latter who is credited with helping to topple Communism in Eastern Europe –- will be canonized this Sunday. In effect, they will, as saints, join the church's eternal hall of fame. And it's estimated that two million travelers will be in Rome to witness their canonizations.
