two weeks从这段的第一句话“Last Christmas I went to Hollywood for two weeks．”(去年圣诞节我在好莱坞度过了两周的时间。)可以判断出时间是two weeks。

Last Christmas I went to Hollywood for two weeks. My best friend was living there. I traveled by plane to Los Angeles, which took 13 hours. My friend picked me up at the airport and drove me in her car back to Hollywood. At first I was disappointed at the city because it looked rather dirty. However, after I’d recovered from the flight, my friend started taking me to see some wonderful sights. She lived in a beautiful house up in the mountains. The place was very beautiful and seemed like a part of another city. She drove me through all the expensive areas where the houses are absolutely enormous. We went to Disneyland and spent a whole day there. I didn’t think I would enjoy it very much, but I did.
