We are a family of 5 (3 kids 16,13,and 9)planning our first cross-country trip from PA to AZ, wanting to see Grand Canyon, Arches, Yellowstone, Mt Rushmore, Badlands, Grand Tetons. We have approx. 16 days max next June-July. I know we would like to rent an RV, planning to fly there or back? not sure what's best? I am just wondering if this is our best option for a one-way trip? Most of our vacations are camping in our pop-up, so we are fine with the camping aspect. I have looked at so much information I'm on overload, I'm at the point where I would love someone to tell me to visit here and stay at this campground (basically give me the perfect itinerary). Help???
