(DUBAI, United Arab Emirates) — As summer temperatures soared outside, the world’s largest indoor theme park, featuring popular Marvel and Cartoon Network-branded rides, opened its doors to the public on Wednesday in the Middle East’s tourist hub of Dubai — the latest in a myriad of new attractions here. The first visitors at the 1.5 million square foot (140,000 square meters) -park reflected the diverse crowds that visit and live in Dubai, home to the world’s tallest skyscraper, the Middle East’s largest mall and a man-made island in the shape of a palm tree that is dotted with luxury hotels. Saudi women dressed in abayas, the traditional loose black robes, and the full face-veil, rode alongside tank-top wearing British tourists and Indian families on the park’s roller coasters and attractions. Several families with young children complained that some of the rides stalled several times.
