Need an SUV for an upcoming golf trip.. Looking on the Skymiles site and found the rental I want for 36k miles.. Small print says that the actual car rental company I choose may charge taxes and other fees.

Knowing how much fees and taxes that ATL tacks on to a typical cash/credit rental (I travel there twice a month), I'm wondering if I am wasting 36k miles since the rental car company may nail me with $30-$50 a day in fees and taxes.

Anyone ever use Skymiles to rent a car, and if so what was the damage on taxes?

Thanks
