In the rooms I've been in (Concierge Floor) at the Hartford Marriott Farmington the card that must be placed on the bed in order to receive a change of linen more frequently than once every three days is located (and completely inaccessible) under the glass desk top.

To me that indicates that hoteliers' bean counters (not only Marriott's) have realized that "green room campaigns" are not only PC these days (with the resultant favorable publicity), but also a form of expense control.

They hadn't converted to "Revive" bedding the last time I was there (a three-nighter) so the program amounted to them not having to launder three sheets three times each (not to mention pillowcases).

I've posted before that I was not a particular fan of the "Revive" bedding for reasons having to do with preferring to sleep under less-heavy covers.

(Of course, Westin's Heavenly Bed features both the comforter and feather blanket so you can choose either option).

If you think about, it's a brilliant move in terms of economizing on laundering -the duvet cover is replaced (besides between guests) every three days (no options offered), the equivalent of avoiding the cost of laundering two top sheets.
