If you reserve a Marriott Advance Purchase Rate, the rate rules state prepay in full, non-refundable if cancelled more than 1 day after booking. If the rate is not prepay, then the cancellation rules are different. I made the mistake of booking a 7 night stay in Boston at the tune of 3K under a non refundable advance payment rate and made the phone call to Marriott. The CSR told me I automatically had 24 hrs. to cancel. As a side note, I have not seen this written on the Marriott site.
