Anybody (calling Taro, calling Taro...) have experience with the offsite commercial parking lots at Narita? Unless I am misunderstanding the price sheet I'm looking at, it sure seems like a good deal. Cheaper than sticking the family on the train to the airport, and I am guessing it's just as convenient (except that I can't chug a beer en route).
Anybody know whether these lots are safe and convenient?
