Tips for first road trip with baby

Give me all your tips for road trips with baby! LO will be 5 months for a 6 hour road trip. Will be staying in an Airbnb. So I’m looking for tips on:

1. keeping baby occupied in the car,
2. making sure she naps on the ride,
3. and any crucial things you’ve learned to bring when staying in an Airbnb!

TIA!
