Thanks for all the positive feedback. It makes all the work worth it. Now I need to "steel myself" before CAMEL. Since the trip will be only half as long, I hope I'll be able to post photos a little more quickly.
I do strongly suggest that anyone planning on taking the Hong Kong-Singapore segment this year (or next?) consider seriously going to Angkor Wat. Unless Regent is doing a "reasonable" add-on, I'd just arrange it on your own. Air was easy from Bangkok (and I think also from Singapore), and our hotel was amazing with a spa beyond belief (and not very expensive).
