National Park Trip

My husband and I will be flying to Sacramento to visit family and then plan to hit the following on a roadtrip home:

1. Yosemite
2. Sequoia
3. Death Valley
4. Zion
5. Arches
6. Rocky Mountain National Park

We will end up in Denver and fly home from there. We will have approximately 10 days for the drive to Denver. Any advice on must not miss areas of any of these parks and additionally nearby lodging (affordable preferably) would be greatly appreciated!

If you had to cut parks out, which would they be?
