Hi Cortney,
The customised map for the Magic Kingdom Theme Park currently shows the area of the New Fantasyland expansion, but not the individual attractions that have either just been officially opened or are still under construction inside that area. As the grand opening of the New Fantasyland took place just last week, I would imagine that you will see some changes take place on the maps online in the near future.
The map does already now show the newest attractions of the Storybook Circus area including the new location of Dumbo The Flying Elephant, Casey Jr Splash N Soak Station, The Barnstormer and the Fantasyland Station for the Walt Disney World Railroad.
My best advice to you would be to keep checking the
Customised Maps section of the Walt Disney World website frequently between now and your upcoming trip for updates. I do hope that you find that the updates have been made before you leave home.
Wishing you a magical trip filled with magic which will last a lifetime!
