I know it sounds like a ridiculous request, but I live in Orlando, and am supposed to be driving to Gatlinburg tomorrow, and with them expecting 4-17 inches of snow in the next few days (thanks to Sandy), I need a 4-wheel drive vehicle to get to our cabin now. My rear wheel drive vehicle isn't going to cut it. Hertz told me that all their SUV's are now 4x4 or AWD vehicles. Is the same true with National? It would be insanely cheaper for me to utilize the Aisle to get an SUV than to get it from Hertz ($200 difference at least). Their call center people didn't know, and I can't get to anyone at the counter for Alamo/National @ MCO.
