Radisson Blu Hotels in Ha Long

The room was actually okay, but there was one issue that really frustrates me. I was traveling with three friends, and when we booked the room on Ctrip, it was configured with a king-size bed and two twin beds, which was exactly what we wanted. But after booking, we double-checked at the hotel, and it turned out they only had twin beds, not triple beds. We tried to book a new room, but they could only find it on a different floor, which was inconvenient. In the end, the three of us were squeezed into two beds, and we were charged an extra two or three hundred yuan for sharing a twin-bed room. What's frustrating is that I booked the room for three beds, but for that price, I only got twin beds, and only one room. Why is the room configuration on Ctrip different from the actual configuration at the hotel? I made a wrong reservation, overpaid, and my stay was compromised.
