Yellowstone road trip with family, my checklist?

Taking my family to Yellowstone for a week this summer. We are from Mexico. Four people, one rental car, and way too many devices. so I'm trying to get everything sorted before we leave.

Here's what I prepared,

• Download offline maps for Yellowstone, Grand Teton, and the drive between stop
• Screenshot hotel, campsite, and rental car confirmations
• Pack layers, rain jackets, refillable bottles, a cooler, and bear spray
• Keep a paper map and basic first-aid kit in the car
• Bring car chargers and two power banks
• Buy snacks and water before entering the park
• Check Verizon, Tmobile, and redteago prepaid esim
• Set everything up before the trip

Anything obvious I forgot? Advice for esim? Thank you!
