So my DH and DS have planned a last minute trip to Denver next Friday. They will be needing to rent a car from the airport (flight comes in the 21st around 7pm) and will return it late Monday night for an early flight out (6:30 Tuesday morning). We have never rented a car before so does anyone have any advice to get a good rate. Due to his late arrival and early departure, we will need to rent from the airport for the extended hours. Rentals are running around $350 for those days! That may be normal, but OUCH! when your not used to renting! Thanks!
