I came back from NZ at the beginning of the week, I flew with Air New Zealand both ways via Hong Kong. Due to time, I didn't stop over, so just had 2 hours at Hong Kong.
I don't travel well but found the trip went well. We travelled economy but were impressed with the amount of leg room. The food was OK and the entertainment was good (you can pause the films, make up your own play list for music)
I am mixed on if I would stop, last time we did and it was great in Singapore as others have said Sentosa is lovely, however I personally almost found it easier to go through the time change once instead of in stages.
Hubbie went via L.A on the way out and found it a bit of a nightmare with the immigration process.
Good Luck!
