Away rotation question

I'm a third year interested in pediatrics, and my home institution is in a smaller town and has a medium sized peds program. For personal reasons, I'm planning on applying primarily in one or two large cities, and several attendings recommended I do away rotations at a large program for comparison. I applied, and while I got a spot at that hospital, it's a rotation that I'm not very excited about (my last choice). Should I go anyways to get an idea of how things are run and if I'll fit in, even though I'm not thrilled about the subject matter? Or would it be better to stay at my home institution for the month and hope I get a good idea of things during interviews?

Thanks
