I don’t think short or vacation visits are sufficient to determine a move. You need to spend significant time in a place, experiencing all seasons, before deciding to move there. What you might experience on even a lengthy vacation is not the same as, say, renting a place in a town you might be considering. The day-to-day living in a place will enable you to see what the ups and downs of routine life there will be like. For example, people may love winter in FL or AZ, but one summer in either place (not a week’s visit) may dim those rose-colored glasses. Or not. You need the whole experience to make an informed decision on something as significant as a move. You may find that the political climate is or is not as important as the weather. You need to explore neighborhoods, counties, real estate—just exactly where are those houses that look good to you and fit your budget really located? What surrounds them? Who lives there?
Given that no place is perfect, immersing yourself in a new locale will help you decide just how happy you will be with that place’s imperfections.
