CY are the way to maintain Marriott loyalty for their endless consistency and professional friendliness...... when I'm going to 4 different cities a week, I want that Marriott quality consistency for quick check-ins, internet & irons that work, someone at the front desk at 5am who knows how to send a fax, etc. If I'm spending fewer than, say, 6 waking hours the extra amentities of a FS are lost on me, as well as the longer walks to parking vs. the CY layout.
Many days, the multiple locations of Courtyards save me hours of rush hour driving by having a property quite near a client or event venue, as opposed to a center city or airport FS.
I do like the moderne design of SHS lobby and rooms, and those are becoming a favorite near Hobby, and especially on the ATL transit train line!
