And apologies if this should have been posted in Asia.

I'm flying to Tokyo for my first visit. I'm only there for 4 1/2 days, but with an AA fare of $473 from JFK, who could resist (especially with VIPOW upgrades to Business)?

I've done some preliminary research and it looks like the best way to get from NRT to my hotel (the New Otani Tokyo, where I got a rate at $184 per night, which sounds good for Tokyo) is the Friendly Airport Limousine. It that true? If so, where do I get it and do I need to book before I leave? Are there ATMs at the airport that are convenient to the bus?

Any must-see advice for a quick stay would be most appreciated. Thanks!
