Try The Excelsior
No, I don't; however maybe with Hong Kong hotels. It depends on how central you want to stay. Most "chain hotels" offer travel industry rates to air crew. My favourite is the The Excelsior in Causeway Bay. Excellent location, good food and Dickens bar is worth a visit too.
E-mail reservations for the rate. Providing there is 2 of you staying in the room it is worth the money. Failing that try the Ibis in North Point. A good bit cheaper but further out of town.
