Beijing again?

A former student from Sogang is visiting a friend in Beijing and wondered if I could visit her. She is a dear student and has become a friend, but it's really cold and walking around Beijing won't be fun. Also her time is limited and we'd just be able to have coffee or a quick lunch. Seems it may not be worth a three hour each way trip. I have been to Beijing twice in October so it's not like I'm dying to get back. I feel satisfied with my Beijing experiences. So I'm leaning towards no. Then I think I could do a cooking course on Saturday afternoon
