I am having a terrible time at Changi! I am stuck sleeping in the airport overnight due to an early morning transit and have been forced to sleep in the arrival terminal. Contrary to what the posh departure terminals seem to convey the arrival terminal is cold and unfriendly. The staff are rude and unhelpful. Furthermore I would expect a hotspot international airport to provide some sort of overnight accommodation other than an overpriced hotel. The airport has been designed so that absolutely no outlets are available for charging electronic devices. Believe it or not the departure terminal is only available to passengers a mere two hours prior to the departure time. So while travelers such as myself are forced to sleep on cold hard chairs in a wide-open area a safer more comfortable lounge area lies right behind security in the departure terminal.
