A little off topic, but to go along with another comment, while it may not be "policy" (could be unwritten policy, who knows), I have been able to modify a room only reservation very very last minute with no cancellation fee. Maybe it was because I didn't try cancelling it, it is allowed. We had a one night reservation, had already paid for it via the deposit, and had even done the online check in. About 5 am on the SAME day as the reservation, something came up that prevented us from going. I modified the reservation to two weeks later, only paying about $5 on the change of price for the night. All of this was done online. There may have been a "change fee may apply" line that showed up, but I was not charged anything to change it. Maybe if the ressie was for club level at a deluxe, or on a night when they were super booked up, maybe they would have charged something. YMMV, but if you are caught up in something last minute and need to cancel, you might see if modifying the date instead keeps you from having the fee. And if so, get to the checkout page to see what the actual $ is.
