What an adventure! I recently did something similar, moved from Texas to Seattle... drove for 4 days!
You might want to consider getting some heatpacks to put in the styrofoam box with your bettas. You can get these from AquaBid. I suggest you purchase the ones that will last the longest put new ones in every morning before heading out. I would not feed them at all for the 3 days unless you plan to make daily water changes. If you do feed them, feed them very little.
