We are a family of 5 including a 3, 16 and 17 year old and planning a trip to USA. We are on a really tight itinerary as spending most of our time in Orlando, but have a spare 3-4 days at the end of our trip. Is it possible and enjoyable to have 1 night Vegas then drive to Los Angeles and see things enroute? Would we be able to fit in Grand Canyon and Monument Valley? Or where is Sedona and is this more interesting than Monument Valley. Are we being realistic in our timing?
