Thanks for the response. Let me give you a little more info. This will be my first time to Tokyo proper. I have been to Narita several times, but that is certainly not the same.

I am traveling with one other person. She no doubt will have a bit more luggage, but we are not going to be very excessive with the packing. Probably a large rollerboard and a backpack.

We are staying at the Hilton downtown. We are not really on a budget, and would much rather pay a premious for convenience.
