Like the OP I will be overnighting in NRT and have booked an award stay at the Hilton Narita. I have 24 hours so I will follow the suggestion here and the other threads of going into Narita town for a nice, leisurely walk.

I have a couple of questions regarding this overnight stay.

1. I'm arriving on AA and departing on CX. Is there a left-luggage service in either airline's terminal(s)? I will have two big suitcases and do not fancy schlepping them around on a shuttle bus.

2. Is high speed Internet access available in the room? Fee? Wi-Fi in public areas of the hotel?

Thanks!
