Interesting. High floor/low floor/near elevator have been there for a while; I never understood why "AWAY from elevator" wasn't an option and evidently it still isn't. (It is on some other websites.)
The pillow thing is a very brave move on Marriott's part. Imagine the inventory and logistics of moving feather and down pillows here and there throughout the hotel every day. Some high-end properties do this; I wonder how well Marriott will be able to execute.
