We schedule an extra day every third day on getting somewhere stretches. When we are there we usually schedule an extra day or two at each destination to allow for changes or bad weather. Extra time built in here and there allows for some adjustments if needed with a minimal number of campgrounds to actually change dates without disrupting the rest of the schedule. We just returned from a 7,600 mile, 23 state, 5 month long, 34 campground trip with all reservations made in advance. Made a few add a day or two, subtract a day or two changes along the way, but didn't change the schedule really much at all. We don't do boondocking so want to be assured we have a spot and know where we are going each day.
