Thank you all for this very helpful information. We are doing a B2B on September 15 from Vancouver to Yokohama (14 nights) and then Yokohama to Yokohama (12 nights) on Celebrity Millenium. We arrive in Yokohama at 7am and leave at 7pm. Is it feasible for us to take the train into Tokyo for a few hours and get back in time for the 7pm departure?
