My family(wife and two kids, aged 11 and 13) and I are in the process of planning an epic trip starting in Las Vegas, travelling to the Grand Canyon, possibly to Monument Valley and Canyon de Chelly, to Palm Springs via Joshua Tree, on to San Diego, up through LA, along the coast, up to San Francisco, across to King's Canyon/Sequoia and back to Vegas for flight back to England.
We've got three weeks. Is it realistic to think we can do this without having to drive for more than a few hours every other day or so? I'm also a bit stuck about what is worth seeing between Flagstaff and Joshua Tree - we'll be staying overnight on this stretch.
Any other useful tips would be appreciated such as where we might meet/avoid huge crowds or traffic congestion. Looking forward to your replies.
