I'm a solo traveler and retired, and those two things play a role in my trip planning. I plan my trips via expressways first. Then check to see if there's places I'd like to see on the way to or from. If its just an Interstate day, I figure 300 miles, drive about 60 MPH and with rest areas and gas stops, that turns into about 6 hours and gets me to my next FHU CG about 3PM. Then I add a day or two of slack before I make reservations for my longer stays. Most times I don't need them, but I'd rather have reservations and not need them than the other way around.
