Got a room booked, got the confirmation email and confirmation number; hotel called us rudely and told us they were at capacity and our res was cancelled. Called Booking.com and they told us, tough luck. They aren’t like an actual travel site that books a swath of rooms, the hotel uses them as free advertising. So the hotel made the mistake and Booking.com did nothing. They helped us cancel our reservation. Never going to use this site again and will tell friends and family that Booking.com and Vermillion, SD Holiday Inn Express is bad business. Shame on you Booking.com for not doing ANYTHING.
