Based on nights. The JW and Ritz are usually outside our corporate guidelines.
MVC: 40%
Renaissance: 15% (although I usually like Ren better than FSM)
Marriott: 25%
Springhill: 10%
RI: 5%
Courtyard: 5%
I have replaced most of my Courtyard stays with Hilton Garden Inns because I hate Bistro and CY offers no benefits to Platinum. This has cost Marriott about 25 nights per year.
