The machine at Celebrity 5 & 10 (Hollywood Studios) remains off stage and may be retired.
Although the official map from penny press vendor CTM Group does not include it, the original 4-die machine in the Rock ‘n’ Roller Coaster courtyard with Coaster designs is still available.
I don’t normally comment on broken machines. Most machines are fixed within 24 hours, and you can expect between 5% and 10% to need repair by the end of any given day. Broken machines are a fact of life with penny presses, especially given the apparent the propensity of children to pound on buttons and turn cranks. There is a machine that has gone unresolved for a while, though: the quarter machine in the Stage 1 Company Store at Hollywood Studios. You expect when you press button A (the 2017 dated design) that the machine will press the designated design. In two visits 10 days apart, though, about 40% of the time the machine will instead press the design associated with Button C. I have brought this to the vendor’s attention twice via their text message reporting system. If you encounter the same problem, let them know specifically what problem you encounter (I never simply report the machine number – I try to include details).
Reminder/update: DisneyQuest closes at the end of business on July 2. The Wreck-It Ralph machines are currently in the store lobby. The other two machines are outside, near the ticket windows. As a result, those two machines should be available even after DQ closes each day.
