Marriott is offering about 90% of their 7500 hotels at off peak redemption prices for bookings made by December 14 and stays through February 28, 2021.
A Marriott spokesperson says “Of the 90% of properties offering solely off-peak rates, about two—thirds of those properties had previously been offering a mix of rates during the promotional stay period.” And that just shows that Bonvoy has been gouging members for redemptions at a majority of its hotels.
