That's a smart way to play the game.

In fact, I want to advise the OP to limit the HK stay to 3 days and then continue on to some place warm (e.g. Boracay, Koh Samui, even Maldives if your budget permits). I like the idea of him celebrating the "water dragon" (I've heard that dragon CNYs are completely off the hook) in China, but also wish him the best vacation possible.

Also, no one's mentioned Taiwan yet TMK; this should also be a consideration.
