I don't like it one bit, it's as bad as the resort fees, but sadly Marriott isn't alone here.
Went to make a booking at the HH Niseko for next March in case the Hilton never opens up and they wanted full deposit within 24 hours with an unclear cancel policy (maybe 60 days?).
Wasn't about to put up a potentially non-refundable $2k deposit on my CC for an award stay.
