After much research, I come now to the experts on Regent cruising for help.

We are booked on two legs of the South America cruise - from Manaus to Callao. Selection of shore excursions are now available, and I wondered if anyone had advice on memorable excursions. I have already pre-booked the one day trip to Iguazu Falls and the post tour of Machu Picchu through Regent.

What is the best excursion for penguin sighting?
Also, any thoughts on private guides vs. Regent tours?

Any thoughts and advice is most appreciated.
