I booked a room of Regent Plaza Hotel through Hotel.com a week in advance. Soon after I booked, the confirmation message arrived in my mail box saying "your room is reserved. You do not have to reconfirm your booking with the hotel." Then, when I checked in, the receptionists told me "we do not have any reservation by your name, and the rooms are fully booked." Then, I called the manager, who insisted that I should leave because there was no reservation. He even told me the reservation system of Regent Plaza do not have anything to do with Hotel.com." Since the security codes imposed by client, I had to stay only in designated hotels in Karachi, but those were also fully booked, so I was stuck in the hotel's lobby, fiercely calling every related organizations to report the situation and find solutions. So, I swear I will never book through the Hotel.com, and never think of staying in Regent Plaza Hotel in Karachi for good.
