Dorm or commute 20 minutes?

I already asked this question, but let me rephrase it...Dorms and meal plans combined I could probably get it it to be around 10-11k. Tuition will be payed for, but books and other fees for honors would come out to be an additional 2-3k. Anyways the university is 20 minutes away. My parents could afford it, but I want to know if it is really worth extra money. Btw I will be most likely living in the Barrett honors dorms at ASU, which are new and nice.
