Cheap Car Rentals in Sun Valley, Denver

We were unable to rent a vehicle. They called last minute and canceled our reservation.

i booked a van with enterprise through Kayak on my family vacation. when i get there, not only did they not have the 15 passenger van i booked. they had nothing so my family and i were running silly trying to find something else. HORRIBLE.

I showed up and they did not have the vehicle that was reserved, they said that they had left a voicemail the day prior, but I did not receive a call or a voicemail. The staff had no other solutions or recommendations for other companies to get cars from and were very rude.

Received a voicemail when I landed in Denver that they no longer had a car for me. I was already on a time crunch and had to scramble to get another car at the last minute.

The Denver location (Welton) called the day of my reservation and said they didn’t have a car for me. Then told me “tomorrow isn’t looking good either.” Why wouldn’t I go to the top of the list the next day, if they didn’t have a car for me on the day I reserved? What stupid game are they playing. I have never experienced this at any rental car company. Thankfully, the Boulder location honored my reservation the next day. I had to get there, of course, and spend money on a hotel. Absolute fail for the Denver downtown location. Deplorable

I searched for rental cars at the Denver airport but it gave me a rental location far from the airport. I ended up having to rent from the airport location at double the cost. Very unsatisfied.

I was charged double after not booking the correct location which I called and confirmed months in advance with an Avis support rep. Horrible experience.

My reservation search was for Denver International Airport pick up and when I arrived I found that the reservation was made for Downtown! The rate was several hundreds more!

I had selected Denver international airport as the location. When I arrived at the airport Avis they did not have a reservation for me… your company failed to connect the dots on the arrival location for selected and the arrival location you sent to Avis. You failed.

It was a good experience. The clerk was out of small cars but suggested a hybrid mini van that gave great mileage.

Simon the owner went above and beyond for me. The accommodations, the service. He’s outstanding.

Super friendly staff, good value

Handy location across from Union Station. We took the train from the airport (buy your $10.50 tickets via the Uber app) and saved 60% on the car rental Vs. what they wanted at the terminal! Trains run every 15mins..and it’s a 40min trip by car/train either way..

I signed up for Sixt through Kayak. I tried to cancel my reservation, but because it was booked through Kayak, I was unable to cancel on their website, because they said I was supposed to cancel through Kayak. But Kayak also does not assist in canceling. I emailed several times with Sixt, trying to cancel my reservation, and they never canceled it and charged me the full fee. I will not be using Kayak nor Sixt ever again for renting cars.

Avoid renting through this company and Kayak if you can help it. I paid in full and was charged $100 to cancel same day after they said pick up location could be changed….for another $200. I was searching Denver international airport and booked a rental for pick up downtown, not even sure why that was in my search results. It defaults to pay in full so I had no idea. Kayak said they have to be the ones to fix it, they said it had to be kayak. At the end of the day I lost $100 but I can only imagine what else they would have swindled us for. Never again for Kayak or this rental company.

The car was not available for pickup, I could not pick upnthe vehicle despite paying the fee upfront. The site continue to book the nonexistent car.
