Elevator maintenance Singapore Marriott
The Singapore Marriott is in the process of upgrading their elevators. While I expect that will be a good thing in the long run it is a considerable inconvenience during the upgrade period. My room was on the 30th floor and the wait for an elevator ranged from 8-20 minutes. In addition it appears they have turned off the coordination between the working elevators so a trip would stop at many floors to pick up phantom guests. (Maybe the guest just gave up and took the stairs)
I was told they expect the elevators to all be upgraded by the beginning of the second quarter of next year. (Scheduled 6 weeks of downtime per elevator.)
I suggest you ask for a low floor if you have to stay at this hotel.
