We went in March and she didn’t stop by to wave during dinner but was there for pictures in the lobby downstairs. Some people reported she did stop by during dining, so it’s a hit or miss. All videos prior to our visit showed her waving and interacting from afar.
Would have liked to have known in advance as I kept telling our kids that she will stop by. The dinner was excellent and food quality has improved significantly vs years past. The price is also now similar to BOG (was more historically) to reflect that.
