Denver International Airport offers Premium Valet Parking on both the East and West side parking garages. Simply enter the parking garages via the passenger pickup lanes, and veer to the outside lanes. As you enter the garages, you have to go nearly to the end, and then you will see the big entrance signs, similar to the one on the right, for the DIA WEST VALET Parking spaces.
These Valet lots see a lot of high end traffic as they are both expensive, and well secured. These photos are of various police cars within 100 yards, right beside the valet. During shift change it's worse, but this was during the day. I witnessed at least 4 different agencies of police vehicles, types of cruisers, and two different SUV makes and models. The fact that 5 different agencies operate, park, and maintain surveillance expands the jurisdiction on the Valet Parking on either side of DIA airport. In addition, each of the cruisers raises the security level and strengthens the security level with another in dash video camera.
