We decided against it, but not for the reasons mentioned. Both were good schools, so that wasn't an issue for me. My kids really like to get involved with school activities, which could have been inconvenient.
The two school systems are 45 minutes apart. It was really too far for the kids to attend evening activities until we just stayed in the other city.
The deciding factor was the week I was deathly ill and DH was on a business trip. DD would have had to miss school since I was too sick to even drive.
I think we made the right decision now, but it was sure easy to consider not having to pay before and after school care back then!
