Thank you so much Mari, that is REALLY helpful and really appreciate your help as was a bit of a minefield to us!
Just a fewmore questions, hope that's ok...
The Narita express+Suica travel card plus discounted 2 day travel card sounds like a great deal, can we buy this on arrival into Narita on the Saturday afternoon or should we do this beforehand from the UK?
Also, for the 1 day unlimited metro card - will the 1 day (24 hours) start when we buy it (so at the airport) or does it start when you put it in the gate to make your first journey? I ask as on our first day, we will probably just look around Shinjuki where we are staying so no metro journies really need and then will explore more on the Sunday, Monday and Tuesday.
Then for the rail pass - thank you, we will definitely get the 14 day pass as you suggest (what a great deal!). I guess we should have it starting from Monday 22nd April, ending Monday 6th May - does the 14 day rail pass include the metro or is this seperate? If not, we may need get the 2 day unlimited metro pass I think.
For the trains between the different places, should we book which trains we are taking and seats? If so, can you do this when buying the pass or do we have to do it on arrival in Japan?
Thank you!
Lucy
