my first time renting a car, have a few questions. flying into denver airport jan 4th. weather at the moment shows no snow but obviously to far to tell. i booked this
5 Passenger Standard SUV (Group L) SFAR
(L) Toyota 4Runner or similar

is that guaranteed to be 4wd or AWD? im only 24 (under age fee waived) and i got a great deal on the 4runner (or similar) through AAA. i only desire 4wd because we have a day or two planned for sight seeing up in mountains. do i have a chance of getting a 4wd with my group class (not concerned on vehicle type, could be a fiat suv for all i care) i just prefer 4wd incase of emergency. or do i need to upgrade again? this is denver airport by the way and 2 weeks from now. thank you- rick
