The itinerary that was made for us to include all of the areas that we wanted to visit was excellent, you did a great job in fitting a lot into a 3 week period....... There was no one stand out highlight of our trip as we enjoyed every place we visited and they were all individually exciting and quite different. If we had to pick one it would be a toss up between Easter Island and Machu Picchu. Thank you for all of the organization that went into our trip, we did not have to worry about any aspect other than to turn up at the allotted time and someone would look after every detail for us.
Many Thanks
Argentina
Much of Argentina is temperate, with the seasons reversed from those in the northern hemisphere. The far north is subtropical whilst the south and Patagonia are cold temperate. The south is warmest from October to March although there can be rain and strong winds. Southern Patagonia has a harsh winter climate from May to September and has great daily variability, even in summer. The temperature varies with altitude as well as latitude.
