Our next stop is Williams, Arizona. It’s about an hour away from the Grand Canyon which is why we chose it. We stayed at Grand Canyon Gateway RV Park. http://grandcanyonrvparks.com/ Easy access for off I-40. It was nice and worked perfect for a jumping off point.
Williams is small, but full of interesting places to shop and see. If you or your children on into Pokeman Go the place is crawling with Pokestops and Pokeman.
For the reader in you there is a small used bookstore called Persnickety Book Shop that has a nice selection for your vacation reading. There is a Safeway too. We just used it as a resting point for our visit to the Grand Canyon. But if we had more time we would have explored more. http://experiencewilliams.com/
