I wanna stop over in Asia on my way to the Maldives, from about Thu-Sun. Which city is worth staying at?
It's not about what city is "worth" staying at. It's about what miles your using, their hubs, and ease of transit.
You don't have the luxury to stop at a second-level city, i.e. Bali, Chaing Mai, etc. You're be confined to a first level city, e.g. SIN, BKK, HKG, ICN etc.
Which of those cities depends on the miles you're using.
