ABRP to plan the Supercharger stops. Use Google Maps to check out what's nearby at each of the chargers. It's also easier to find them if you know the nearest major business. It's always nice to eat at a Supercharger stop that has a good restaurant and overnight at a Supercharger hosted by a hotel. Saves a few minutes of charging. The in-car nav can also do the whole thing, but favors longer drives and charge stops which result in slightly longer trip times.
The one key trick to road tripping is to charge only enough to reach your next Supercharger stop with 15%-20% charge remaining at destination. The car will give you that information as you charge and while you drive. If that number starts dropping too low while driving (10% for me), slow down for better efficiency. Charging is much faster at 20% charge than at 70%+.
We had a problem in Arizona and New Mexico with fast food and hotel Supercharger locations that weren't allowing restroom use. And closed rest stops as well. Farther east we didn't have any problems, though that might change if COVID gets worse. I did have an emergency container with me but didn't have to use it. Malls are usually good, but may not be open early mornings. Sheetz gas stations(!) or other truck stops should always have a restroom open and food available.
We did have to eat in the car a few times when dine-in wasn't allowed. A lap tray helps with that, along with and "Eat" driver profile. Disposable wipes and hand sanitizer were indispensable. And snacks as a backup.
