Hi guys. We will be leaving LA, CA on July 6th with a goal destination of NYC. We have 3 kids with us and will be renting a minivan and flying back home. On our itinerary is Grand Canyon, visiting family in TN and going to Great Smoky’s NP, then proceeding to visit more family in Maryland and then taking a bus to NYC for 4 days. How to survive this trip with kids, ages 15, 8, 5. We will have 3 longest driving days: AZ to TX, TX to TN and TN to MD. They will average in 10 hr driving days. I am so scared. What to pack, how to pack for such trips. How to book hotels for overnight when we don’t know where we will stop exactly. Please help
