"Hotels.com only sent me an itinerary number instead of a proper reservation number, which led to the front desk staff claiming they couldn't find my booking details upon check-in. To make matters worse, despite arriving shortly after the 3 PM weekday check-in time, I was told the hotel parking lot was completely full. They directed us to a department store parking lot instead. Because of this, my elderly mother, who relies on a walking cane, had to walk for over 15 minutes just to reach the lobby. It was incredibly frustrating and deeply unpleasant, especially since there was absolutely no prior notice regarding the parking situation."
