Hi everyone. I am planning a road trip with my 12 year old son in August. We have 13 days and the tentative plan is Los Angeles - Sequoia Nat Park - Las Vegas - Area 51 - St. George - Zion - Monument Valley - Grand Canyon - Phoenix - Los Angeles. Seemed like a good idea at the time, but am now a little overwhelmed and am worried we will spend most of the time driving. Any ideas as to what is really worth it and what maybe I can leave out? We live in Europe so I got carried away perhaps because of the "when are we going to have the chance to see this again" factor. Any and all help welcome! Thanks!
