Good that this is here
As the father of a 4 year old, and facing a 1.25am flight to Osaka, we thought it may be worth paying S$110 or so for a triple room so that we could get some rest before this flight. In the end we got some sleep, and it made all the difference when we got to Japan the next day.
Rooms comfortable, adequate shower and bathroom and tv if you want it. Basic but comfortable and a good place to rest.
