There's a massive shopping area (duty free!), a gym, massage, swimming pool, shower, lottsa great food places, internet (charge up your laptop!!), a new slide as mentioned, interesting people to observe, etc..
It's not about available options, as much as what you'll like to do and how to cram them in effectively, especially if you're crossing terminals =) over 7 years agoAnswered by JustJesz.wordpress.com via WorldNomads.com
There're 3 terminals in Changi airport all connected by sky trains, so plenty of shops to explore. If shopping is not your cup of tea, cafes are all around the airport too.
