I have a breakfast reservation on July 29th. I've never been to Chef Mickey's or the Contemporary, so I have no idea what I would be missing, if anything. Should I keep this reservation and see if Disney does anything to make up for moving it, or do I just book a new breakfast somewhere else?
You can probably find a video on YouTube to see what the actual restaurant in the CR looks like. The big selling point of Chef Mickey's is more the 5 characters (Mickey, Minnie, Donald, Pluto and Goofy) than the food and even the surroundings. If your family meeting those characters for pictures and autographs I would keep the reservation. If not, you could try for another character breakfast ADR, but this close to your date, I'm not sure how successful that would be.
