Their failure to have a viable no-show process makes one really appreciate Inyo National Forest for the way they handle the Whitney permits.
Here's how it works for Whitney hikers:
Permits for Overnight hikers have to be picked up in person by 10 AM the day of entry, and Dayhike permits have to be picked up by noon the day before. Or at least people must call in by the deadline, or their permits become available to others.
I've even suggested a partial refund for early call-ins for for cancellations, but was told giving money back is always problematic.
I do think people canceling should be rewarded.
