Hi fellow Cunarders.  In around two weeks time, the wife and I board QV in Rio de Janiero Brazil.  Very excited, and counting the days.   Does anyone have any tips/suggestions for embarkation in Rio and disembarkation in San Antonio (for Santiago)?  Our current plan in Rio is Uber from the hotel to the pier.  For San Antonio, our current thinking is Pullman bus from the Terminal Barrancas de San Antonio to Terminal de Buses Alameda in Santiago.  This bus is bookable online for US$6 per
