my $0.02.
train like you have never trained before. hikes, cardio.
you want this to physically be a walk in the woods without the woods - for the most part.
rush, if you must, for sunrise. but realize that by rushing you are also rushing your acclimating. i've seen many folks much younger than me turn back due to lack of acclimating. you won't know how you'll acclimate until you are there. baldy, san g and san j can give you a clue. but san g is only 11,5 and you're going for 14,5. remember, almost half of the hike is at altitude higher than san g.
now i'm a bit older, but i realized that after i had trained for six months to attain my goal that i wanted to enjoy every minute of the journey.
the burgers, as good as they may be, are no reason to rush your trip. they, like the mountain, will be there.
