We didn't stay at the Ymir Hotel though I had checked it out prior.
I agree with your take on the lodge Alta. I don't think anyone on our trip was upset with the rustic accomodations. But at some point there's a difference between rustic and unsafe. Sadly it seems like it may be teetering on that line. Would love to see minimal investments to bring it up to snuff -- work exchange, small co-op. Such a cool spot and the terrain -- as you say -- is excellent whether it's storming hard or sunballs all week.
Now...on to the food.
