its 240, but than they add in fees, tax, more airport fees, = 330.
What i know some people do, rent a car when u come in, if your going to be by someone for the weekend, return the car on fri and have them drive you to the airport when u go back. But that just depends on your situation. Good luck though! U can return the car to your local neighborhood location for no extra fee, even if you rented it in the airport, i dont know if this is the official rule, or the few people i know that did that just got luck!!
Have a great weekend, & happy New Year
