Kudos to Marriott, Elite Rollover Nights popped up on the Marriott.com home page this morning! Point your browser to Elite Rollover Nights
Let's hope Double Nights comes back too!
See earlier postings from MR URL sown below. Bopttom line: All 2009 nights count --- those stayed and those bonus nights earned during the "double-nights" promotion periond earlier this summer and bonus nights earned as a perk of the MR credit card.
The calculation is simply that your total 2009 nights that EXCEED the renewal requirement for the elite level you are currently on ---- will count toward earning elite status for 2010.
Not as coplicated as it sounds --- see: http://www.marriott.com/marriott.mi?page=eliterollover----for details
