I don't tend to spend only one night in a locale. If a location is popular enough to warrant advance reservations it should be able to hold our interest for at least 2 or more nights. Should something happen to stop us from arriving as "scheduled" go ahead and change it knowing you've still a place to lay your head whenever you arrive.
Still tenting but since we use a car to do get around seems about the same as RVing on that level. I also do a lot of reading in advance on itinerary stops so I know some of the things I want to do before we go. Conversely, when time is constrained makes it easier to decide what sights to save for a later trip.
