We’ve been on several vacations throughout the past few years, and my husband would rely on our laptop GPS to navigate, especially when we would go downtown into the big cities.  It really came in handy when we were in downtown Chicago and also once when we were in downtown Denver looking for a certain restaurant.  It has come in handy and saved us from the frustration of getting lost countless times because my husband would plan our route ahead of time.  If you don’t have a GPS, then you check out Garmin GPS and the savings at Buy.com.
