That’s how it always was in
Disneyland during slow periods. We’d go for a few days the day after Labor Day when the park reverted to early closures and very few people in the park.
Disney studies and analyzes everything. From the number of steps between trash cans to the amount of time a guest will tolerate waiting in line, they enforce these details. This even applies to the FP/Standby quotas for attractions...there’s a range of the number of FPs holders allowed before 10 Standby guests can “merge”...and that’s also based on park capacity.
