I'm planning to stay in Hakone area for 2 days.

I will arrive to Hakone from Kyoto and return to Tokyo. I'm thiking that it would be nice for us to buy the Hakone Free Pass for these days but, do you know if it's possible to buy the Hakone Free Pass inside the free area that includes to return to Tokio?

I've understood that if you go out from Shinjuku (5.000Y) the round trip is included, and if tou buy the tiket inside the free area (3.900Y) it is not included. Is is posible to buy inside the free area the expensive one (5.000Y)?

I don't know what is HFP ¿?

The information that I have to return to Tokyo is from Hyperdia, with SHINKANSEN KODAMA 668 from HkoneYumoto to Tokyo = 3740Y.

That is more expensive than to buy a Hakone Free Pass for 2 days, visit Hakone free area and to return to Tokyo (5.000Y).

Am I loosing something? :)

Thanks in advance.

Where can I found the timetable for the Odakyu line? I don't have the JR Pass.
