You don’t walk Singapore in the afternoon unless someone has thought through the path. Marina Bay is the rare district where someone has — every major building connects to the next via the basement, the second-floor link, or the awning network. The continuous covered walk from MBS to Raffles Place is over a kilometer and you never break the sweat barrier.
These three picks use the covered network at three different times: lunch (basement-heavy), late afternoon (bridge level), and after rain (awning hops). The app routes you through whichever link is open right now — some arcades close between 10 PM and 6 AM and Stay Cool knows.
