I am staying 9/28-10/4, so I made my ADRs on Monday. We're on Deluxe and I had to make 15 reservations. It was terrible and I hope it goes better for you all! It took me until almost 11am EST to get most of what I wanted because the website was so awful. Storybook Dining, Garden Grill breakfast, Le Cellier, and Sci-fi for some unknown reason (something tied to SW:GE maybe??) were completely unavailable for 7 days. I am hoping Garden Grill opens up with the Eat to the Beat packages.
The good news is while the website is slow as heck, availability is there for lots of places. We got the other hard to get places like Ohana dinner, Cinderella breakfast, BOG dinner, a few PPO breakfasts, Fantasmic & Festival of Fantasy packages, etc.
