Disney has extended the Early Morning Magic event with dates that continue through the end of September. Disney’s official word is available here: https://disneyworld.disney.go.com/dining/early-morning-magic/. While new dates are scheduled, they do not yet appear to be bookable, at least online. So if you are trying to book July – September, be aware that the event is not “sold out,” it is just “not yet available.”
Beginning with the week of July 10th, the event will move to Sundays and Tuesdays rather than Saturdays and Tuesdays.
You may remember that the website reviewed the event positively with some caveats.
