Dubai just opened the world's largest indoor theme park - here's what it's like inside

Dubai is already home to the world's tallest building, artificial islands, and the world's first hotel with a rainforest. Now it can add the largest indoor theme park to its list of world-firsts.

Measuring 1.5 million square feet, IMG Worlds of Adventure - which opened on August 31 - is a nod to characters from Cartoon Network and Disney's Marvel universe.

The $1 billion (£750 million) theme park was opened by Dubai's ruler Sheikh Mohammed bin Rashid who toured the building on its opening day.
