Thanks all for your suggestions. I am going to Kyoto directly from NRT, spend the next 2 days there and on the third day come back to Tokyo and spend another 2 days before leaving for NRT.
So I get the JR pass (myjrpass.com has it for $268 while others have it for around $280-$285), exchange it at NRT and have it stamped and take the Narita express to Shinagawa and take a Hikari to Kyoto. On my way back from Kyoto, stop at Tokyo station.
1) In kyoto how do I get to Westin Miyako? I understand I should go to Karasamu exit and do I take a Cab? Bus? Hotel Shuttle? Which one is relatively easier?
2) Should we get a day bus pass in Kyoto? 2 day pass?
3) How do we travel around in Tokyo? Metro Pass? Or some form of JR Pass + something else? Do we buy it the first day at NRT? or once we get to Tokyo station? Does it make a difference?
4) Getting from Tokyo station to Grand Hyatt. What are our metro options?
We are 5 adults and 2 toddlers so we might need 2 cabs if we go that route.
Thanks again for your help.
