Mickey & Minnie’s Runaway Railway is a new ride coming to Disney’s Hollywood Studios on March 4th, 2020 and is replacing The Great Movie Ride. The ride will launch with a bunch of new opening day merchandise, and it appears as though there will be two new themed MagicBands as well. One will be a teal standard MagicBand, and the other will be an Annual Passholder exclusive band. My guess is that both will be Limited Edition, but we don’t know for sure yet. Here’s a preview of what they look like, and I’ll be posting another article in March with better pictures when they hit shelves.
Thanks to @WDWNT for the pictures.
