Re: Best time of day to fly from London to Sydney with kids?
 

We have travelled with kids and used the transit hotel in Singapore airport. You can book the rooms for 6 hour blocks, definately worth it to have a bed and own bathroom! The curtains are the blackout type so it's possible to sleep at anytime. Pool is also great with a bar and towels provided. Make a reservation to be sure of getting a room.

We also did the free bus trip into Singapore and visited a shopping centre. Got lost in shopping centre and nearly missed the bus back!

New Terminal 3 at airport is also great, plenty of quiet areas and a kids play area.
