The back way to Cooper Spur:
From Hood River, take Highway 35 south 13 miles to the down of Mount Hood. The speed limit drops to 45 here and there are several buildings including a general store/cafe on the right at a major intersection. Turn right here (there's a sign that says 'Cooper Spur 10 miles') and follow the road 10 miles to Cooper Spur resort. In my experience, when coming from Hood River this way is about as long as the other way.
Regarding the Tilly Jane Cabin vs the hut, go with the cabin dude. It's pure luxury compared to the hut and not a significant distance away. Besides, That time of year, the road is almost certain be closed at the lower gate (at the Cooper Spur ski area) so you'll be approaching via the Tilly Jane trail which takes you right past the cabin. You could continue on to the hut but it's probably less than 500 feet elevation gain and you might find it buried or filled with snow. In the summer it only takes about 30 minutes to walk from the cabin to the hut. If you're really prepared to climb NF routes then the small amount of extra distance won't make any difference.
Also, the TJ Cabin is about 3/4 of a mile east of the Cloud Cap parking lot and at the same elevation. Doing NF round trip in a day from TJ is comparable to doing it from Cloud Cap.
In any case, enjoy, good luck, and post pics!
