8. A Bat Museum

The theme park would also offer an opportunity that most Batman fans must surely already be calling for: a museum dedicated to everything related to the world’s greatest detective.
As well as articles of interest, including the earliest comic books featuring the character, the on-site museum could collect rare and valuable merchandise and film and TV memorabilia including costumes and props.
Basically, it could become a Mecca for all Batman fans who want the theme park experience, as well as somewhere that celebrates the property behind the entertainment, telling a concise and most importantly fan-targeted history of the property in a way that has rather unthinkably never been seen before.
Everything that's everything from the movies, stored in one place...

With Disney likely to bring in more Marvel presence at Disneyland and Disneyworld, the stage is set for DC to link up with Warner Bros to give one arguably their most famous property an opportunity to pull back some focus, and the museum in itself would represent an essential destination.
