Understandable.I'm disappointed. There's something so satisfying with leaving dinner with your picture in hand.
There's a very decent chance the photo will appear on your MM before you finish eating. I'd checkTwice (once at CRT, and once at princess dining in Epcot), the picture they took wasn't so good, and when they were delivering them to our table, they invited us to have our retaken, which we did.
Now, I'm afraid there won't be anyone advising guests of needed retakes. Not happy about this change, even though we will be getting Memory Maker.
