Worst

Make a easy drop off sign or box. Many of us were waiting in line for drop off until after many minutes, someone said drop the keys off and go...so making that a more smooth operation would be helpful. Also, I think the car I was driving needs a wheel alignment.

I waited over an hour for a customer service agent. This has never happened in my life at a car rental agency. Once I got to customer service it was very fast, the agent was very courteous, professional, and efficient. He was one of 4-5 other agents, but the other agents seemed to take much longer. This appeared to be part of the extreme wait time. I also did not get the car I wanted. I reserved a 4-door sedan, but got an SUV. I was so tired and hot (it was 90 degrees in Denver) from waiting that I didn't even ask for a different car, I just wanted to get out and leave. Drop off was much faster, but I noticed that the line for others to get their cars in the morning, was just as long as it was for me in the afternoon when picking up the car. The shuttle to the airport was ready and waiting.

Terrible drop off time. Almost missed the flight.

The agent tried to get me to pay more for a car I didn't need.

Horrible customer service. It took over 1hr and half to get the rental, a lot of hidden fees that they only give you at the counter. Charge separately for individual insurance policies which they tell you a different thing before you call. The airport pick up location is horrible. Overall would not use this company again.
