@msp Hi Marc-san,

You can reserve a seat on the Narita Express from this site:

And, there are also discount passes.

We wish you a great trip!

We stayed at Hilton Tokyo in Shinjuku and it was a very nice room with roll in shower. Hotel overall was very nice and in a nice location.

Just had a look and it’s lovely but the accessible room still has a bathtub and not a roll in shower

Thanks for your help, really appreciated
