Susan, we are booked on the Manaus to BA segment this January. I don't think we have started planning the shore excursions as we have 2 trips between now & January. I confess it is my husband who is the master trip planner. I am just arm candy.
However, three years ago we did Iguazu Falls with a private guide pre Antarctica cruise & last year we did 10 days in Peru with 3 days hiking Machu Picchu. You will love these trips.
See you onboard.
