It's not impossible to imagine. Guest information can be sent and received wirelessly and conspicuously using RFID in Magic Bands and mobile phones. The queue for Everest or RnRC can read your name without needing to tap anything, and rides like Dino or Guardians can send you a ride photo without needing to tap anything. A guest profile with a photo/description, reputation scores, and list of significant activities (attractions ridden, characters encountered, current missions etc.) could be sent to improv actors backstage which could be quickly memorized and used for improv storytelling. After an encounter the guest's profile could be updated to reflect changes in reputation or other data. This was the main appeal of setting Galaxy's Edge in an original location with original characters. Instead they opted for a much cheaper execution; mobile phone mini-games triggered by physical locations or QR codes. Those should have been the polish and supplements to the original robust role-play system instead of the entire experience.
