If you want a 5 star hotel (it's your honeymoon, after all!
), try the Marco Polo Hong Kong hotel. Among the top hotels in HK, it's the best value for money (the Pennisula is too overhyped, IMO.)
In Thailand, I just stayed at cheap places so I can't give you any suggestions.
What airline will you fly on? If you have a choice, I suggest EVA Air, Evergreen Deluxe class via TPE. It's a very good value for the money, almost as good as business class, but for only about 20% more than regular economy fare.
