I plan to drive my 2015 Toyota Corolla and thinking of giving 5 days to the trip. My plan is to start the trip on 26th June 2016 and planning to reach Austin on 30th June 2016. With 2 drivers for this road trip, do you think it's a reasonable time frame or should I add one more day? Which cities I should have an overnight stay? My friend and myself (both of us in our 20s) would like to explore a little bit of the states we will cross (esp. Utah's national parks), so any tips/suggestions for not-to-miss places/things will be appreciated.
