I would also like to visit Asia in the next few years...
Mike I would join you but that itinerary seems very Viet Nam-centric.
Yours look like the Dec 9 - Singapore; Bangkok/laemchabang,thailand; Ho Chi Minh(Phu My), Vietnam; Hue/Danang(Chan May),Vietnam; Hanoi (Halong Bay),Vietnam; Hong Kong, China.
I am looking to see more - Singapore, Hong Kong, Japan, - like the April 11, 2013: Hong Kong, China; Taipei(Keelung),Taiwan; Nagasaki, Japan; Busan, South Korea; Jeju Island, South Korea; Tianjin, China; Shanghai (Baoshan), China
The prices are GREAT, though. $1499 (inside) or $2399 (veranda)
