Another alternative is to just rent a car for that long road trip which I’ve done in the past.
That being said, I think far more people worry about daily mileage than you think. People think in terms of time spent driving, not distance. They tend to assume every hour is 60 miles and reality is for most it’s nowhere near that. I’ve had my wife lose her mind that the car is warning about range with 25 miles remaining and she’s 6 miles from home. Humans tend to be REALLY bad about estimating the distance of something but really good about estimating time.
If someone were to ask you how far your office is from the airport, I bet you’d respond with how long it takes to get there, not how many miles it is away.
