Where I am going, I'm just half an hour away from school. At the time I applied, I had to weigh GAS vs HOUSING.
How much is housing per year? How much gas would you spend round trip every day? How much in food everyday?
Where I am going, even though it is relatively close to home, I decided it would be cheaper in the long run, and more beneficial for me to stay on campus.
One thing my older sister stressed to me was that she really regretted not staying on campus. The college she went to was five minutes from our home. She still says she missed out on so many activities because once she was home, she didn't want to go back out.
Living in the dorms is absolutely great. The food isn't THAT bad, and it allows me to be more available for campus activites.
If you need someone to vent to about this, feel free to pm me.
