I've been adamant for the past few years now that Epic Universe won't have the best capacity (even though it has a lot of attractions on opening day) in Orlando, and equal to that of Animal Kingdom. Problem is that attractions like Donkey Kong, Werewolf, Racer Rally are low capacity, while the higher capacity attractions like Monsters & Ministry are not reliable enough yet.
With that said, this park has a lot of "filler" experiences like shows, interactive experiences and great dining to reduce the impact of low ride capacity.
