Read the following article and answer the question. Article: Late that afternoon I took the train back to Sydney. There I found another surprise waiting for me. My room at the hotel had been given to somebody else and they had no room for me. Harkin had known my travel plans and had planned everything. How could he have booked the room only for three days? There was nothing to be done but to find another hotel. The waiters were happy to find me a new hotel, and when I said that I was happy to stay at the airport, thinking it might be cheaper than staying in the city, they suggested the Holiday Inn at the airport. There was one small matter: the room rate was 300$ per night. The best hotel in Katoomba had wanted only 145$. I asked if there was anything cheaper they might suggest but they warned that most hotels would already be full by this time. The hotel was far from the train station, so I had to take a taxi, as 25$. On the way to the Holiday Inn, we passed a hotel just two blocks from the Holiday Inn that advertised a room rate of 104$. At the desk I asked if their room rate could go down a lot. "No, this is a 4star hotel," the waiter told me. "In that case," I replied, "I'll just walk the two blocks to the cheap hotel." But she warned me that they were probably full and that if I didn't take the room, it might not be available when I came back. Finally, I decided to take the room. The room itself was big, but the air conditioning couldn't keep up with the Australian heat. I couldn't get to sleep until about 1:00 am. Question: Why did the writer take a room in the Holiday Inn finally? Answer:
The answer is:
The room was in great demand.
