A fully indoor theme park on Yas Island themed around Warner Bros characters — DC superheroes, Looney Tunes, Hanna-Barbera, Scooby-Doo. Six lands, 29 rides, several full-size dark rides and a couple of serious coasters.
The interior detail is unusually good: Gotham City is built out as actual streets you can walk through; the Looney Tunes section is bright and cartoonish without being aimed exclusively at small children. Useful with kids, useful on the hottest summer days, less interesting if you don't recognise the franchises.
