I quite like the slow Hakone Tozan railway to get from Hakone Yumoto (a few minutes past Odawara on the Odakyu line) to Gora, and thence by taxi or hotel shuttle to the Hyatt. It's a single track railway that at least twice requires trains going in opposite directions to go through a rather complex maneuver to get by. It would be fun to take this in at least one direction, I think.
