We have made journeys in which we have both stayed overnight, days, weeks, and months .. it has just depended on where we were, where we wanted to be, and what was happening. A few places we have stayed a week before moving on, only to think back and wonder why we didn't stay longer, so have gone back and stayed a month.
One of the bonus points to traveling full-time is all the options. One thing we have had to consider when traveling to see relation/friends is to watch the weather .. sometimes it is best to change the routing or to stay over until the weather gets better .. sometimes we have traveled with reservations, and at other times we have called before noon to make reservations ..
My personal choice is to know in what area we will be in either tonight or for the week .. sometimes there are special events going on in an area i.e., Annual Festivals, etc., so those times are usually more expensive for lodging of any kind .. have found that a couple of times the last few years .. so researching is kind of important.
The first 6 years of Full-timing we came onto this site frequently, and since then only a occasionally, however, my experience has been that RV.Net is the main reason we have stayed on the road all these years - since May 2004.
