Yes, we have a wide range of add-ons to choose from. Denver gets a lot of snow and is surrounded by mountains, so it’s a good idea to add guaranteed all-wheel drive as an extra when booking.
If you plan on engaging in outdoor activities while in Denver, you will definitely need a car like an SUV. For those staying in the city, a sedan is the perfect fit.
It is possible at some stations and for some car categories to rent a car with a debit card. An additional ID may be required. Otherwise, all major credit cards are accepted.
