I'm not really happy about the news either.
I'm at Universal July 29 - Aug 3, then Disney Aug 3 -17 with free dining. I kind of wish I had scheduled Disney first, then Universal. I'm not sure if I can change dates and keep my dining, and...well, I did get the meals I wanted.
I guess what I'm most concerned about is that people who booked in September, thinking to visit during a lower crowd time will move their trips to August to avoid the opening.
But...does anyone know, can you move your dates and keep your free dining?
