Guests traveling aboard National Geographic Explorer or National Geographic Endurance arrive this morning in cosmopolitan Buenos Aires, set on the Rio de la Plata, and check in to the fine Alvear Art Hotel (or similar, Explorer) or Alvear Icon (or similar, Endurance). In the afternoon, we have a guided overview of the city, seeing its Beaux Arts palaces, grand boulevards, and the famous balcony forever associated with Eva Peron. In the early evening we gather for an informal reception and a drink at the hotel.
