I spent 7 days in HK last march and it was a good length of time, but still had several more places I wanted to see plus spent a day in Macau, which could have been a few days. Also Shenzen and Guangzhou are easy to visit from HK, so that is a definite option.
Another trip I'm planning is Samoa and American Samoa. Although I'm only looking at a week for those (although for island lovers i think it would be a good 10 day trip). Or for something different you can go to any number of remote tropical island places like Kiribati or the cook islands.
You could do a 2 city trip like Singapore/HK, or Beijing/Shanghai.
For something different Sri Lanka and Mauritius are probably close enough for 10 days to be good.
I've got many ideas, my problem is often picking which one, rather than not having an idea!
