How convenient is the Prince Sakura to the Shinkansen? To Ginza? As a base for Tokyo exploration? We've been before but the folks we're traveling with haven't -- and we've only stayed in Shinjuku or Ginza -- never Shinagawa (and we'll definitely be heading to Ginza for lunch and/or dinner which is a big point in favor of the Hyatt).
Trying to determine whether to stay here on a 22000 JPY/night rate or stay at the Hyatt Centric on points.
Big plus here seems to be better room size (plus upgrade possibility as Titanium), access to shinkansen (assuming it's as close as I think it is), and Titanium benefits (though we'll have 2 rooms so will need to see if they give us benefits for both).
