On a cross country trip we built in travel nights to stopover at a Loves then drive to a campground every other night for two nights. Kept our sanity and allowed for hiccups here & there along the way. Too tight of a schedule is too much pressure!
PS. Cave country campground near Mammouth cave is perfect! Try it!
Your "camp ground plan" is an interesting one. We've debated about making overlapping reservations for the very reason of a snafu that slows us down or the desire to have more time for a newly discovered, last minute gem to visit. I've started paying more attention to where we might find Cracker Barrels along our planned routes. How are the Loves? Is there a lot of overnight noise and traffic or is it not too bad?
We have a couple of days at the NP campground reserved.We are looking forward to just being able to park the rig and have less than a 15 minute walk to the visitor center and other amenities.
