63: It's October! There is a quota of 60 on the Cottonwood lakes trail, 24 are held back for walk-in requests. There is NO WAY you will not get the permits you need if you show up.
I am sure lots of people reserved the permits back when summer was in full swing, and you can be sure half of them have already decided not to go.
Now that the permits are handled online by a nationwide system, it is high time they start giving out partial refunds for cancellations. I am sure that would free up a lot of slots in the future.
