I e-mailed a similar question and got the following bad news:

Dear Mr. Schobel:

Thank you for contacting Marriott Rewards with your inquiry.

In regards to the Point Saver Awards, I need to make you aware that they have been put on hold. Due to some program updates they will not be offered again until possibly the end of November or December.

I apologize for any inconvenience this may have caused.

If I can be of further assistance please let me know.

Sincerely,

Brian Sorensen
