We're all relics, Merav. Welcome to the forum.
Grandfather actually really hasn't changed all that much in many, many years. Some of the changes in there are the addition of "portraits" that change as you walk by them, the removal of some of the special effects in the main room (You can't climb the ladder any more, and the sound effects don't always work when you grab for the gold nugget.), and the removal of the waterfall out front. Grandfather's still in the shower, isn't he? And I believe the fellow in the rocking chair has been the same for a long time. I have found that my memories of the SDC of yesteryear are usually better than the real thing actually was. I would hope that the place could keep its charm. Our children will remember the place, but will likely remember it for the rides and not as much for the charm and mystique.
