The long-awaited Jewel Changi Airport will officially open its doors to the world next Wednesday. About half a million people have signed up for the public preview currently being held from April 11-16, with about 60,000 visiting on the first day. Visitors can now shop and dine at about 90 per cent of Jewel’s 280 shops and food and beverage outlets. They can also check out other attractions, including an indoor garden that spans four storeys and the world’s tallest indoor waterfall. The Straits Times explores the ins and outs of Jewel.
