Leaving tomorrow for Fla

We have been working to drive a reasonable amount so we do not arrive very tired. We have two drivers so that is clearly easier. We have two dogs so like to stop every two hours for a few minutes of break for them and then we change drivers. We are now averaging 400 ?450 miles per day and it feels pretty good. We get off the road earlier and relax. We have in the past pushed it hard including some 24 hr stints. Two days from LA to Madison WI was a push. No more. We love the journey now that we take it easy and if after 300 miles we are tired we look for a place to stop. That is rare but keep it as an option. I would suspect you are on a schedule with limited time for the trip so pushing a bit more is desirable. At this time of year you aren't probably going to experience bad cold so that is good. Just don't risk your safety by pushing when not alert. I can say that adding an hour to the day because you slow down makes the same distance easier especially when the roads are poor. Bad roads where you out.
