Sierras de Cordoba as a popular Anglo-Argentine vacation spot

[yd_mtl]

Why were the Sierras de Cordoba (Cordoba Hills in Anglo-Argentine lingo) more popular among Anglo-Argentine tourists and retirees in the early/mid 20th century than Mar del Plata and other beach resorts along the Buenos Aires province coast, despite being farther away from the city of Buenos Aires and its suburbs?

On a related note, did Anglo-Uruguayan tourists/retirees (with their base in Montevideo rather than Buenos Aires) go to Piriapolis, Punta del Este, and other beach resorts along the southeastern Uruguayan coast, as opposed to the Sierras de Cordoba?

Perhaps the dryer climate and the health benefits associated with it. I recall reading about Che Guevara's family spending time in Cordoba for relief of
his asthma symptoms.

Is it possible, then, that Anglo-Argentines felt even more of the need to spend vacation time in such a drier climate, with its health benefits such as for those with asthma, than Argentines as a whole, who on the whole have spent more time in Mar del Plata, Punta del Este, etc.?
