Jewel Changi is a great alternative shoot location if the weather is bad! Rachell and I came to the airport as a last resort when it started pouring before our shoot. It was on the weekends so it was mad crowded, but in the end, we still managed to get some pretty shots!
A recommendation would be to come here on the weekdays, or scout for quieter corners if weekends are your only option. Try to go to the higher levels because people tend to crowd only at the lower levels right in front of the giant waterfall. We definitely had to deal with people walking past us very much, but we still made it work!
