As you are debarking in Brazil, be prepared for all manner of delays, real or imagined. On our last debark in Rio, the tour escort apologized for the inordinate delay and explained that "if Brazil could make something difficult for tourists, it would, unless it could make things more difficult" - his words. So fair warning even if all your ducks are lined up in a row, don't relax until you are on the plane. Good luck!
