Another option, since you mentioned going off-trail, is that the Nelson Lake Trailhead out of Tuolumne Meadows almost ALWAYS has availability. It's an easy hike from Nelson up past Reymann to Vogelsang, and from there you can tie into Daisy's itinerary.

We did a chunk of this last year---it's on our website.
