Bad business practices. They screwed up the reservation, were AWARE that the reservation was set for the wrong day, and not only refused to make accommodations, date changes, or refunds, but even refused to admit that they were at fault. And, after reading reviews from people who have stayed there, I feel like I dodged a bullet.
