Singapore boarding took 3 hours ( some 4 hours ) the worst I have ever encountered, no communications to passengers, no staff had any idea what was happening, PA was distorted.
Admittedly two ships were in port, but one had the impression it would have been the same even with one ship.
Talking to passengers leaving the ships ( Voyager and Mariner ), both leaving passengers had nothing but bad comments of the ships, especially the Mariner.
Good size and had fridge and no plastic shower screen to stick to you.
Good clean city with great transport and plenty to see.
Nothing much to see really and port is so far away from city and sky was full of smoke.
Can walk to town and all around city, lots of little things to see if first time. Good cheap bus trip to Casserina Shopping Centre by public transport to see the suburbs and for good shopping and eateries.
