TheRealDuckie (and friends) is working on a complete, functional replica of Walt Disney World in Minecraft, and has posted an update to Reddit. The Magic Kingdom is largely down, with the rides all ridable, and working restaurants. Epcot is underway. The files are available as free downloads.
This project started on the Reddit Creative Server and was later moved to Redstonehost.com. It took us 4 months of work and over 25 Cast Members to finish. We have recently started on EPCOT and will be continuing the resorts soon. As each park is finished we will release another download. As always, these downloads are free. We seek no monetary gain.
