I'm thinking about a trip to Patagonia for March. One of the must-dos would be hiking the W. It's probably too late to book any refugios (and trying to find out for certain, we're getting a really bad vibe from the organizations through which those could be booked; emails take forever getting answered, there's no online availability information, and they're expecting all personal information, including passport numbers, to be submitted through non-encrypted forms), so we're considering going camping.
So... Just how cold does it get at night on the W in March? Can we at all rely on being able to rent tents at the refugios in March (my 5 year old Chile Lonely Planet says they sometimes run out "in high season" - anyone with recent personal experience?), or should we really bring our own? (Call me a wimp, but I'd vastly prefer not having to carry that weight.) Do the refugios sell meals to campers, or only to people staying inside?
So many questions, and it's proving so completely frustrating to find recent information; or really any information at all from someone not trying to sell me a full package tour. :/
