We will be in Death Valley on Saturday (below sea level) and on Sunday will be in Lee Vining. Monday we will be on Tioga Road (10,000 ft). I'm sure many people come from Death Valley to Yosemite... Has anyone had any problems with altitude sickness doing this? Wish we had more time to adjust, but we only have Sunday which is our travel day. No MAJOR hikes planned- all under 2 miles, but still a bit concerned since I had some issues on a hike our first day in Grand Teton.
