I chose Columbia.
Haha, yea. I was pissed. I had received my interview for Minnesota a few weeks earlier and I was more interested with them than Temple. That being said, they didn't give me any other options...
I had some inconvenient interviews, but you just have to suck it up sometimes. I was lucky and had extremely understanding professors and was allowed to make up exams, practicals, quizzes, labs whenever I needed. Just try to be nice and understanding that you may be causing an inconvenience for a lab course. I think if you offer a good solution when you ask your professors for make ups, they may be more understanding.
