Tokio - Kyoto - Matsumoto - Narita

Hi there,

I´ve been reading the FAQ for a while, what a good service you are offering here! Congrats.
But as many travelers I want to check if my itinerary worth the pass 7 or 14 days; here we go:

We arrive to Narita and first of all we have to take N'EX to Shinjuku.
Our main plan is to go around Tokio area using subway JR net. (included right?)
Whiting the 7 first days we will do a 1 day visit to Kyoto, I think al ready get that those tickets are included on the Rail Pass. (included right?)
On day #6 we move to Matsumoto from Tokio visiting some friends there. (included right?)
On day #8 we have to come back Matsumoto - Shinjuku - Narita (N'Ex)

So the question is;

For sure we will take 7 days pass, if all the itineraries mentioned above are included,
But it worth to take the 14 days pass or 7 days pass + Matsumoto - Shinjuku + Shinjuku - Narita.

Thanks a lot and congratulations again.
