We travel 1000 miles each year to see the lights and WDW. The Osborne lights have been around as long as my children have been alive (20 and 16) and used to be able to walk up the street to see them. They, while a bit over the top, are a symbol of Jennings Osborne's phylanthropy and his drive to always do it bigger and brighter. When neighbors complained, lawsuits and all, we supported them even though the traffic was an absolute nightmare over the Thansgiving & Christmas holidays.
Over the past few years Disney as consistantly cut back on the holiday decorations, merchendise, etc. and have simply watered it down to the point of it being nearly a waste of time. The decorations are stale and should be refreshed, not removed and the Osborne lights are one of the few areas Disney has refreshed each year and made just a little better each time we visit. The kids always search for the black cat, the Osborne's stockings, and point out Little Rock on the globe.
Simply put, they are a major reason we visit WDW each and every Christmas instead of other times of the year. As so many other posters have stated, this has become a tradition to many families, if they are moved I would hope they are treated accordingly and given another new life as Disney did when they moved most of Jennings lights to Orlando.
