Allow me to showcase the reason in 3 pictures Take a look at the statistics. Scroll through your social media newsfeed these couple of weeks and what is the most common thing you see, be it on news or shared by friends? JEWEL If you manage to make a trip down to Jewel and stay till the Waterfall Light Show in the evening, just observe the number of people whipping out their phones to insta-story / Facebook Live the show. It makes my hair stand. Imagine each instastory reaches out to approx. 200 followers, multiply that by the number of insta-stories posted and one will then have the realisation that whatever costs involved was worth it. One can pay for advertising (posters, facebook ads) but one can never pay for publicity (i.e. word of mouth, reviews etc.) Furthermore, one has to understand the cruciality of an airport and its surroudning infrasturcture. The Airport serves as the first impression of a country, being the first and the last thing travellers see when they arrive and depart. It's how a country bades a tourist goodbye or hopefully, a see you. And Singapore has indeed done in right. I personally think much credits has to be given to Chairman of Changi Airport Group, Liew Mun Leong, who was also once the CEO of Capitaland whom I believe has a significant influence in this project. A big kudos to everyone involved in this project.
