Yep, this was what I was thinking of. If you are thinking of going to the Gotemba Premium Outlet, give it a skip. If you do travel to Hakone from Tokyo and back, make sure you take the Odakyu Limited Express Romancecars and no less.
i just went hakone on the 2 days hakone free pass which cost 5000yen. did not pay extra to take the romance car, instead just took the limited express train.
There is a hiking trail at goba, the scenery there is nice.
