My wife and I will have a layover from Friday 05:00PM (arrival of our flight from Hanoi) to Saturday 07:50AM (departure of our flight to Surabaya/Indonesia) on our next trip in October 2013. We’d like to use this 14h 50m (NIGHT time) as pleasant as possible. Is staying in Ambassador Transit Hotel in Changi Airport recommended? Is there any night tour that is recommended? Please advice. Thank you.
