In my experience, Marriott's have had notices at the front desk warning that they do place a hold of $XXX on the debit card and that the amount will be unavailable to the card holder for up to 10 (maybe diff #) days after checking out. I wonder if that scenario is more of what the OP wanted to avoid.
