The entire summer is slow. Probably the worst it’s been in a while. Keep in mind they were proactive with the “discounts” too.I just checked online and there’s still tons of rooms available over the next few days across the resorts with the exception of Poly and GF. Fireworks spots, perhaps?
Ask any travel agent and they will tell you Disney is suffering badly compared to last year and even prepandemic.
At this point, I don’t think the “discounts” will give them the result they anticipate. Disney has managed to alienate so many different segments of guests that some of them, have just given up on Disney. (Pick your reason). That percentage 5-15% are what make the difference between packed parks and full hotels vs sub-optimal attendance and bookings.
