I would strongly suspect that Pausanias believes that 3 days in Ushuaia in August could prove to be a slight letdown for somebody whose hotel reference point is Aman,I have visited Ushuaia,although a long time ago,my reference point at that time was not Aman,and still is not,however I distinctly remember the place as a dump.If somebody wants to be able to say that they have visited,by a definition that includes having overnighted,what I believe is the southernmost town in the world,a late flight in,folowed by an early departure is advisable. There are lots of NICE places to spend 3 days in in Argentina!!!
