Patagonia during Easter weekend

Hi,

I've read that Easter weekend is a very big travel weekend in Argentina, but I've also read that museums and national parks are closed. Did I read both of these correctly?

I'm planning on spending several days in Patagonia, and these days would most likely coincide with Easter weekend (Semana Santa). Am I going to find myself stranded with nothing to do because things in Patagonia are closed for Easter weekend? Does this include Glaciar Perito Moreno and other national parks, or might I be able to find a tourism company that could get me over to there?

Thanks!
