First, could you tell me about travel arrangements for your last holidays? Did you experience any difficulties in your journey? ,M: Well, our plane didn't take off on time. It was delayed 5 hours. So we didn't get to Lhasa until 4:00 in the morning, and we were very tired when we got there. But we managed to book a car at the airport through a car rental platform. And it dropped us off at the hotel in time around 7:00 o'clock for breakfast, so that was alright. ,F: And how was the hotel? ,M: Well, we were a little disappointed with the room, but the Patella Palace was just a stone thrown away.
