Day care is usually a big problem when it comes to issues like this. I was faced with such too.however, I would go for the one i can afford even though it means driving that far. It's only for a short period. Another important factor is you may have to find out their time. (Opening and closing time). If you have a clinical assignment at 6.30 and they open about 6-6.30am. You can be sure of running late to clinical site, or if you have to stay up in school until about 6-7pm when day care closes by 6pm...you know, you reallly have to put all those into consideration and be able to come up with one that suits your schedule...
Goodluck
