I'm having trouble with Points Savers for Grand Cayman Marriott. It is listed as available from April through October, but when you go to reserve it shows none during any month until the Seasonal discount starts in September. I'm trying to book a 5 night stay starting August 25th.
You are right it looks like the Point Savers discount is not available at this property during the month of August. I'm guessing that only a limited number of rooms were available for that promotion and they have already been booked. If your able to plan your trip in late September instead you would be able to use less points for your stay.
