You can rent a 3BR or 2BR apartment at University Villages. They are located on the backside of Highlands close to Blackjack Road. Only thing is they are unfurnished. They do have a fullsize washer and dryer and basic kitchen appliances. If you have blowup mattresses, you shouldn't have a problem. Easy access to campus.
Best I can remember the rates for a weekend are this:
3BR - $350
2BR - $250
YOu can call them for more info at 662-323-7615.
