On the walkway from MK to the Contemporary there are bricks with people's names and dates. What is the story with these? Is it similar to the Leave A Legacy at Epcot?
I can't speak for certain about the WDW ones, but the ones in the esplanade at DLR between DL and DCA were available to purchase in the early 2000s. For around $200 (give or take) you purchased a brick, and received either an acrylic or wooden replica for home. Our replica is acrylic.
Our brick features our names and wedding date. (mine and the kids feet)
