I've skied the High Route - Symmes Creek to Wolverton both ways - East to West and West to East. Great trans-Sierra, highly recommended. We didn't do these tours back to back and the trips were separated by 9 years.
You may not be aware of this, but the park service allows you to cache food,supplies in a shipping container located behind the cabin (summer campground office) at Tuolumne Meadows campground. They have rules on the type of container for your food, and when you are able to put your cache in their container. I believe the last date is October 15, but check with the rangers.
We did a tour from Tioga to Mammoth one spring. We got a ride from Caltrans as we were walking up 120 from the gate 5 miles W of Lee Vining.They dropped us off at Tioga Pass Resort saving us ~ 8 miles and nearly 3,000 ft of walking. Their truck stopped and they said get in, so we loaded our packs, skis and us in the back.
