Hi. I'd really appreciate your help. We are a family of 6 (four kids ages 12-3) and are planning a road trip next July/August out West. We have three weeks and I'd really like to be able to start in LA and work my way to Yosemite, then Yellowstone and then Grand Canyon (or different order).
I'm thinking 2-3 days at Yosemite, 3-4 days at Yellowstone and 2-3 days at Grand Canyon with the rest spent on driving and other small pit stops.
Is this too much or possible?
