Difference between a "show" and a "parade" at Tokyo Disney Resort
Tokyo Disney Resort Parade has no capacity. Most shows have capacity.
There are two main types of entertainment at Tokyo Disney Resort: shows and parades. Parades are one of the shows, but parades are basically held only at Disneyland.
Tokyo Disneyland's parade goes along a long route, so many people can see the parade in one performance. While parades can be viewed by thousands or tens of thousands of guests, "shows" are held on a stage at a fixed time and place, so there is usually a fixed capacity.
Therefore, a lottery system is used for the "show," and you must win the lottery to be able to see the show.
The lottery for this show uses a system that allocates winners within the time of the deadline based on a comprehensive projection of past and current admission numbers.
The Disney Resort uses a system that does not allow for empty seats at any given time.
