7 or 14 day rail pass

Like so many others, I'm debating whether to buy a 7 or 14 day rail pass. Traveling in mid-April, I'll go first from Tokyo to Kyoto and back with some side trips out of Kyoto. That trip is worth the 7 day pass. At the end of my two week visit, I'll be traveling Tokyo-Hakone area and back. I can't decipher the schedules sufficiently to see if a 14 day pass would be worth it, And then there is the Hakone Free Pass, http://www.odakyu.jp/english/freepass/hakone_01.html, and I can't figure out if this replaces some of the Tokyo-Hakone transportation expenses.
Any advice is welcome.
