Congrats on the acceptance.
If you go to Arkansas you will live off-campus. There is only one dorm for grad students and it is horrible. But apartments are cheap. A nice one bedroom near campus averages around $300-350. I live in a large 3 bed/3 bath and the total rent is $750.
I would recommend driving. I think it would be considerably cheaper and the drive isn't too bad. I've driven from here to Florida several times. You can do it easily in one day, or two days at a slower pace. (all depends on what part of Florida you start from)
I don't know a soul there... how do I find a place before arrival? Do they offer furnished apartments; I really don't want to buy beds, furnitures and move it around? I would probably stay in hotels first and then search for places...right?
So.. you really don't think the dorm is the way to go?
