This is only for curiosity, but I am curious. I just returned from a cruise that ended in Valparaiso. I debarked at around 9:30AM, and my plane back to the USA left at 9:30PM.
What would you say would be the best way to spend those hours? Getting to the airport on time, of course, but also seeing a little of Santiago or Valparaiso and Vina del Mar, visiting a winery in the valley just East of Valparaiso, etc.? Making sure that the luggage is secure as well. How would an expert do it, assuming that you are not met by a friend at the dockside?
