It is a frequently asked question on this board as to the security requirements at individual properties.  It is probably time to put together an updated list of policies at various hotels.  It is obviously a pain in the ass for someone to undertake this on their own, so my thought was that we frequenters of this board could post 2 or 3 properties each and then I could undertake to cut and paste the results into a comprehensive list.

I will divide the answers into three subheadings:

Key required at all times to either show to security or to operate room elevators,
Key required after a certain hour of the day (please list the hour.
Key not required at anytime.

When (if) TER posts this messages, I'll reply to it with the categories above.  You can then reply to the subheading to assemble the list.

This would be helpful to me, but my thought was many other travelers would find it helpful as well.
