So has Disney? This meet and greet announcement is only special as its indoor meet and greets.
Over at Epcot Anna and Elsa meet ouside the Royal Sommerhaus, Jasmine on the Morocco Stage, Snow White by her well, Aurora on a side path and various Mickey and Co characters on the sides of Spaceship Earth. This doesn’t include Joy or Pooh who are relatively far from guests and truly are distanced away.
At Animal Kingdom I’ve Russel doing meet and greets at Rafikis Planet Watch Train Station back in August or honestly even earlier than that.
Studios I’ve seen Goofy and Max doing meet and greets over by Peevy’s Polar Pipeline/Holly and Vine. That doesn’t include the distanced meet and greets throughout the park either on Hollywood Boulevard or from Tower of Terror.
So yea the announcement is only special cause the location is indoors.
