This is my first post so interested to hear your responses. We are a family of 5 from England planning a 3 week trip starting with friends in Boulder, then Arches, Canyonland, Bryce and Zion national parks. Then onto Vegas, Grand Canyon, Palm Springs (possibly?) and then finishing in/around LA. Done 2 American road trip before - both times before we had kids - so keen to plan things better this time! All tips gratefully received, especially anywhere good to stay between Zion and Bryce, a family friendly (if they exist!) hotel in Vegas and advice on staying around LA. Kids want to see Hollywood, we want quiet beaches, cycle rides and nice restaurants - is there a compromise! Does this trip sound doable? Also in and around Grand Canyon/Utah - are there lots of gas stations - or do we need to plan that carefully too?
