I am looking to use points to stay 5 nights at Marriott's Cypress Harbour in June. The chart indicates I need 140,000 points for my stay. However, when I enter the dates to reserve my stay find I need 160,000 point (down from 180,000) and an e-certificate plus 2 upgraded certificates for each night. Why the difference in points required and why do I need upgraded certificates?????
Any insight into this would be helpful.
