Capacity closures are not a shutdown of the park, but rather a shutting of the gates due to an overabundance of guests. If you’ve been inside a Disney park during peak seasons, you may have wished they’d start shutting the gates, but in reality a capacity closure is pretty rare. Since Magic Kingdom is the most popular park, capacity closures happen most frequently there, followed by Hollywood Studios and Animal Kingdom. Because of Epcot’s large geographical size, it is highly unlikely to close due to capacity. Capacity closures always happen in phases, starting with a Phase One closure that just restricts admittance to casual “walk-up” guests. If total guest numbers continue to climb, Disney then starts restricting more and more types of guests, with priority going to guests that have in-park reservations or are staying at Disney Resorts.
