Thanks for the very helpful suggestions on how to do this trip without flying. We will have to rent a car, and stay in Airbnb's along the way. I know it's a very general question, but in general - what are we up against? I will be the only driver and can't drive at night. I'm also a bit nervous of aggressive drivers. Also - what ID's will both of us need? And will the rental car company allow a cat? We're new to Mexico, retiring here. Would love any info / suggestions. Thank you!
