For any of you surprised by Hagrid, I remember gringotts being down time after time during the opening day.
As we were standing in line, we’d hear an announcement that the ride was “now operational,” people would cheer, we’d stand up and hope to move forward a few feet.
Fast forward about 10 minutes and we would hear, “we are experiencing brief technical difficulties”.. everyone sighed and would sit on the floor.
Waited 4 hours for one of my gringotts rides. The ride proceeded this way for a few weeks. Pretty standard with UNI in first few weeks with advanced new ride systems.
