Response from OP....

You have all pretty much convinced me that the Transit Hotel was probably a mistake, but it is too late since it is non-refundable.

It was not a financial decision. It was a decision of convenience. It seemed like a good idea, if I was to be awake 25 hours flying, to just crash immediately by 1 am or so, sleep as long as I wanted, and wake up refreshed at a reasonable hour in the morning to explore Singapore .

As opposed to arriving in a hotel in Singapore closer to 3 am....possibly later if flight is delayed....waste a good chunk of the next day sleeping and take longer to adapt to the new time zone.

I will only be in Singapore 2 more nights after I arrive before heading to Thailand so I wanted to also maximize my daytime hours. I figured a sleeping pill at 1am would knock me out, regardless of the noise or whatnot at the transit hotel, and I could enjoy a good complimentary breakfast in the airport before hitting the town.

The responses here seem to be nearly universal that I made a mistake. I didn't realize getting into town was so easy and quick. But my reservation is non-refundable, so I am committed. Next time I will consider other options as outlined above.

Thanks.
