Schipol hotels
 

Which hotels are walking distance from the aiport terminal?
Is there a Hilton or an IHG property at the aiport (I get free upgrade at these)?
I would appreciate any advice. I will have a car though if I am walking distance I will give up my car when I arrive.

Both the Hilton and Sheraton are onsite - Sheraton actually connected via a walkway, and the Hilton mostly an inside walk with a short outside portion at the end, they also have a shuttle.

Also onsite is the relatively new CitizenM which is worth a stay if for no other reason that to experience the place. Tiny pod-like room, but a huge comfortable bed, a quick walk from the terminal, inexpensive, great bar with friendly staff. I'll be there in a couple weeks.
