It would depend on your flight reservations if they leave from Lima or Cusco. Spending a night in Lima allowed a rest before the early morning flight out of Lima without the added expense of a flight back to Lima and hotel room. The cost of the 2020 trip is the same with the shortened itinerary. In the 2019 itinerary, the last night in Cusco is the white elephant party and the lunch in Lima it the only time you go into central Lima with a nice farewell lunch at the historic Casa de Aliaga. The tour now stays in the Westin Lima, but it is a great and new hotel with a delicious buffet breakfast. However, even without this last day in Lima, it would still be a great trip but would have preferred it with the extra day. As a thought, why not extend a post night in Cusco to explore on your own, which was not possible in the old itinerary.
