Who stays at hotels? Private accommodations are the way to go. Lenas is great, IF the Marte is open (it's almost never actually open though). Your best bet in South America is to hang out in one spot for a while waiting for the snow. When you start rolling all over the place, you end up missing storms or rolling up to a spot and finding everything closed because of wind or high avy danger.
Its not like up here. If theres a huge storm, they dont really bomb...they'll just wait until it settles then open. Or, they'll just open and leave it up to the people riding to discern safety. If you weren't going with a guided group, I would at the very least want to have an Avy 1 with some extensive real world experience.
I'll put it this way to you. In a slide a few years back, half the searching patrollers forgot to turn their beacons to search to look for buried victims. Do you trust your life to avy control done by patrollers like that? Go with someone who knows.
