I ended up switching my reservation to National - we'll have to get a cab over to Collins, but I don't need to worry for the next 3 weeks as to IF we'll get the right rate. I got a sweet deal - Jeep Grand Cherokee for $53.50/ day, unlimited miles (I had to pay $.37/mile with Hertz). I did something I never do - prepaid for a full tank of gas. $75.83!! Makes me so glad I have a hybrid at home I can fill for under $30. But there's no way I'm going out hunting for gas on Christmas morning. ETA: Even with the full tank of gas, my rate is less than with Hertz. Blah!
