Actually the SEZ layover now 12:45 layover instead of 15 hours so technically as of May it was new. It is in fact the worst trip we have arriving at the hotel not before 8am and the wakeup call is 6pm. I kid you not!
Am I missing something here a 5 hour flight and what's the difference between a 12.45hr and 15.00hr layover - well possibly the chance of a sleep to a sleep and a nap i guess.
For 12.45hrs Science says stay awake as long as you can and sleep right up to wake up call.
