Stock up on snacks. Everyone gets the munchies when on the road for some reason. Last time we took a road trip, I ordered a box of snacks from Amazon and it worked out great.
Cozy things like hoodies, socks, pillows, and blankets are a must. And don't forget your chargers, headphones, and batteries!
Trash bags, paper towels, Lysol wipes. Those are my go-to's for clean up.The worst thing on a road trip is a dirty car!
