From the terminal to the bay, without the taxi queue. Changi Airport is ~20 minutes away.
We collect from and drop off at the hotel's main entrance driveway on Raffles Avenue.
Mandarin Oriental, Singapore is at 5 Raffles Avenue, looking over Marina Bay beside Marina Square. It is roughly twenty minutes from Changi, and close to both the Esplanade and the Marina Bay waterfront promenade.
A flat S$85 in a Luxury MPV, S$95 in a 13-seater Combi or S$225 in a Mercedes S-Class, whatever the traffic. Your flight is tracked, so an early or late landing changes nothing, and 60 minutes of waiting is included while you clear immigration.
Going back to Changi is S$65 in a Luxury MPV. A pickup between 23:00 and 07:00 adds S$20 — worth knowing for the early-morning flights to Europe.
For meetings across the CBD, corporate hourly hire from S$85/hour keeps one chauffeur with you, rather than re-booking each leg.
