Living and working in China most of the year, and having travelled many times to HKG and SIN, you can never go wrong with the fun, shoppping and beauty of HKG. Go to the top of the peak, take a daytime or overnight cruise to nowhere on Star Lines. Enjoy the fine hotels and great Asia or Western cuisine. As for the flights, I cross the big PAC again this Tuesday. Eastward wears me out even though we have dinner and fly into darkness from NRT.
Flying west, even though we are always in daylight, I sleep so much better. And as posted, dont worry about the food. It will be there whenever you want or need it. Enjoy your trip.
