Brent, this is not what you asked for, but my favorite mode of acclimating is to go up to Horseshoe Meadows and camp two nights prior to hiking up the Whitney trail.
Horseshoe meadows is at 10,000', and has walk-in camp sites. There are several easy trails to hike where you gain a 1000 to 1500', so you could do that to enjoy the area.
I am sure others will have some good suggestions, too.

This is excellent advice and the trails are very scenic and you won't get worn out for Whitney.
