I vaguely remember someone mentioning that there was some kind of day tour around the city of singapore where you get to see the sights and I think he said you didn't have to go through immigration or worry about visas etc coz you are just in transit. Can anyone with experience of this provide any more info/links?
I'm arriving in Singapore 2:30pm, departing 10pm.
