aleph raises an important point. If getting from Shinjuku Station to your final destination is easy, go ahead and train it. If not, a bus direct to the hotel can be easiest on the suitcase's wheels!
aleph (and others): Feel free to drop me a line at
[email protected] if you want to be included in the Tokyo "database." (There are a handful of FTers here, although we've just started getting together recently.)
Off to the US tomorrow (via the NRT Express from Shinjuku - although personally I prefer the Skyliner.)
