I'm leaving soon for two weeks in Asia (first time there!) and would appreciate packing advice from anyone that's traveled there. We'll be in Hong Kong for 5 days, Bangkok for 4 days, and Cambodia (Siem Riep, Angkor Wat) for another 5 days. It looks as though the weather in Hong Kong will be quite a bit cooler than the other two very warm destinations. We'll be cycling in Cambodia, so that's an easy capsule for daytime, but will be going out at night.

Of specific concern is being respectful of cultural norms there and dressing appropriately for exploring local temples. If you have experience, I'd love to hear about it!
