I just booked the CX 566 redeye from HKG-KIX for the May Golden week holidays. Luckily, redemption ticket still available in Business class. I plan to go to the airport and get my dinner at the Pier. Then, when on board, I will skip the meal and try to sleep as much as possible (the aircraft, as of now, is a 330 with lie-flat seats). Upon landing in KIX, I will then take the train to Kyoto. Not hopeful of an early check-in at the Hyatt Regency, but I will anyway enjoy walking around the area for a few hours in the morning.
