Hi Nicebloke,
Not exactly the question you asked, but have you considered spending two nights at Mammoth Lakes? It is "on the way" from Petaluma (assumes you go via hwy 120), and allows you to sleep above 8,000'. I am told that sleeping at higher altitude is as, or more, important for acclimization. There are many day hikes to choose from a short distance from town. I personally do not do anything longer than 5 miles immediately prior to a "Big Hike".
Then, drive down to Lone pine on Sat morning, and still do a short hike. I like to hike up to the E-Ledges (and above if you are comfortable with it) as a final "tune up". This also insures that you are familiar with the trail head, and initial portion of the Main Trail (if you have not done it previously)
Good luck with your hike.
John
