This will be my second cruise on HAL Rotterdam. My first was last spring (2006) from Lisbon to Athens. I will be traveling alone this time. Being a retired pilot, I am curious about the Antarctica Flyover Excursion out of Punta Arenas. Does anyone have advice or is planning on taking it? I also plan to be in Valparaiso 2 days in advance and in Rio for several days after. What hotels are "sponsored" by HAL?
