I'll just deal with the steps in Shinagawa Sta. It'll make finally getting in my room more satisfying.

edit: I guess if the short taxi to the Prince costs chump change, I'd roll with that. Besides the incline tho', it's
really a short walk.
It’s been a while since I’ve stayed at the Prince properties in Shinagawa, but if I remember correctly, they operate a shuttle bus service to and from Shinagawa Station from all of the hotels. I think they ran once every 20 minutes in a loop, making a stop at all three hotels—Shinagawa Prince, New Takanawa and the Sakura.
