Welcome to RVing. There are so many beautiful places to see its tempting to shove too many into one trip. Schedule in time to relax and linger as well. Visit some interesting towns along the way for lunch or supper and you can stretch your legs.
The 4 places you've already chosen are great for doing just that; stick with those 4 for the two weeks and you will be on vacation. More than that turns into a nonstop tour and you come home more tired than when you left. RVing is more than a checklist of things to see; it's about the journey and family time with loved ones and friends.
