Nice photos. Hakone pass should have an option for longer stays but nothing much to do after 6pm. Moto Hakone feels like a ghost town with only Lawson lit up. When did you visit?
The 2 days pass is based on dates/days rather than timing right? Meaning if i leave Shinjuku at 9am on a Monday, i need be back in Shinjuku by Tuesday 2359? Theoretically speaking...
