I am booking a trip for my parents (mom's 55th bday). I think they would enjoy the Australis cruise from Ushuaia to Punta Arenas, and I want to base the rest of the itinerary around that. Here is what I am thinking. My concern is whether they will be seeing similar things between staying in Argentinian Patagonia and the cruise.
Arrive Buenos Aires (couple of days there. they have been before)
Fly to El Carafate (stay at EOLO or Estancia Cristina or maybe somewhere else?). 3 nights
transfer to El Chalten for 3 nights. Not sure where to stay there
transfer to El Carafate Aiport and fly to Ushuaia. overnight and take the cruise.
arrive in Punta Arenas 4 days later, fly home.
