Fred - CHINOIS is masterful. I confess I'm not up to speed with the dual requirement for geographic symbolism coupled with a pithy acronym phrase. I'll move CHINOIS over to the 'name this cruise' section. You've got my vote.
I plowed quickly through Frommer's website looking for something succinct and recognizable re: Vietnam. TONKIN or MEKONG were top of the heap. THIT has no potential to be a hit. As for me, life is a CABARET!
A bientot, Anne
