We just booked the China Discovery cruise - just the sailing portion as we were going to be in Japan during that time anyway and this fit into our schedule and flight back to the US from Japan and it is relatively easy to go to HKG and back from PVG to Japan. We are cutting our Japan trip short to go on the Yi Dun on October 24.. I wish I knew more about the ship, crew, food, entertainment, excursions, etc., so if anyone knows anything or finds out anything please let me know! If not, I guess we will find out!
