Sorry to keep going, but I had other thoughts come to me after I hit "send."
I never had a problem with the LaL stones, or to others the "Tombstones." In fact, my family and I had our pictures done and placed on the stones when we went in May 2000. We did it because we liked the idea that our pictures would be up there for 20 years and in a sense we would always be in Epcot even when we were not in Florida. So I never saw it as a tombstone, death related type of symbol.
To see it become a memorial does upset me and others. Mainly because, as Merf said, it was created to commemorate a trip(s) to Disney World and to help people celebrate the coming of the year 2000. As I stated above, let's leave death references out of Disney and allow the "escape from reality" idea remain strong and true.
