We are planning to drive from Chicago to Orange County, CA in early October. We will take the I80 to I70 to I15 route. We would like to do this in 4 days. Question 1: Advice regarding the 3 nightly stopping points on route. Question 2: How feasable to take an extra day and see the Grand Canyon. Question 3: If not the Grand Canyon, any other places recommended to visit. Don't really want to spend more than 5 days on this trip. Any other suggestions and advice would be appreciated. Thanks.
