I plan on one or two nights at Whitney portal, I have to reserve them still.
We stayed there two nights last time as well. I am very aware of the effects of
altitude and plan to camp at 12,000' on the trail.
My husband and I are very sensitive to altitude and did well
on Kilimanjaro this past fall. We used Diamox, which we plan to use again
for Whitney.

If I can take more time off, I would love to spend more time in the Sierra's,
but that may not happen.

Altitude sickness is crazy and you just never know how it will effect you.
