Can't decide to get a pass or not

I'm conflicted about whether or not I want to get a rail pass. If I do get one, it will be a 7-day pass.

Were flying into Osaka on Nov 11th, and departing from Tokyo on November 24th.

Our tentative plan is to travel from Osaka Airport to Kyoto the day we arrive. We'd like to spend 3 days (min) in Kyoto before activating our pass. We would then travel from Kyoto to Nikko, spend 2 nights, and one full day in Nikko, before heading to Tokyo to complete our trip.

As we travel to Nikko, we'd like (weather permitting) to stop somewhere enroute to get some really great views of Mt Fuji. We were looking at a prolonged afternoon, or an over night in Hakone.

We are considering a possible overnight/afternoon trip to Kobe as well as Osaka. Going to Nara does not interest us.

So the main stops we've been looking at are Kyoto, (possibly Kobe & Osaka), Hakone, Nikko and Tokyo.

I've priced it out and emailed a few travel bloggers who have been to Japan recently and have gotten conflicting advice. Some people say to get one, others say to not bother.

Help!
