Ok, so i need your guys's help on something. I'm flying into seattle on may 18th, flying out on may 20th. I'm going to a waterski tournament, and trying to do the whole trip on mileage. I booked a united ticket, but the problem is with the car. All the car companies will rent to me (I'm 21), but charge $25 a day additional as an "under 25" fee. The rental is only 16-20 a day, so the fee is more than the rental. Enterprise is a more reasonable fee, but i cant' rent from them on mileage. To rent on my mileage, it has to be from hertz, avis, alamo, dollar, budget, or national. Anyone have a trick or a method to not pay this underage fee? I hate to pay $200 to rent a car that should cost like $80. Thank guys!
