We wanted to buy a brick and stopped in City Hall at MK a while back. A CM told us she was almost positive we couldn't get one anymore and no one there could support or deny that claim. Even though there seems to be room for some more (not a lot) along the walkway from the CR to MK, I haven't seen any new bricks being laid unlike DL. The option now I think is the leave your legacy at Epcot with that monochomatic photo etch. DW didn't like the "tombstonish" monuments.
