There is a luggage storage service a short one minute walk from Union Station in downtown Denver - LUGDEN. You can make a reservation online - lugden.com, call - (303) 747-5600, or show up as a walk-in. They offer hourly, day, overnight and weekly bag storage. Great place to store your luggage if you're on a layover from Denver International Airport, or going to a concert, or headed to a Rockies game at Coors field and want to enjoy yourself without having to lug your bags around.
With the same standard features as the Traditional line, the Traditional Plus Collection is intended for more rugged applications. Plastic Lockers are ideal for high-humidity moisture applications, as these virtually maintenance-free lockers will never rust, rot or corrode. These lockers are available in multiple configurations and are backed by a 15-year warranty.
I am writing this review because the owner of Lugden, Mic, lost; "gave-away" my girlfriends suitcase when we were in Denver for a wedding the Sept. 15th, 2018 weekend. I do NOT want anyone to deal with what we went through. This seemed like a great idea to check our bags and walk around Denver for a few hours before having to catch the train to the airport, but after only checking our bag for an hour we went back by and my bag was sitting on the side of the van and her bag was completely gone! Again, out there for a wedding! She had shoes, jeweler, expensive purses and pictures of her and her deceased father that she takes everywhere with her to keep him close to her; but her bag was gone. He had no system to track, had zero clue who he had given it and could not call any of the previous people that he had recently given their bags back to them. He quickly ran off in side as I called to the police to get me his liability insurance policy and stated "Oh man I just remembered, her bag was really heavy right? Some guy came by and said it was his bag and there were books in it so I let him take it." WTF!!!!! How does someone take someone's checked bag and run off with it. To make matters worse because we had a plane to catch I called his insurance company the following Monday and his "Insurance Representative" informed me that Lugged Inc has lapsed on their insurance and has zero liability coverage for instances like this.
Terry, there are many storage unit places closer to the airport, but then of course you'd have to rent a car. DIA Self Storage, for example, is less than 10 miles away. You can google map Denver International Airport, then "search nearby" for "self storage units" if you think that's something you might want to do. http://www.coloradoselfstorage.com/
Steel thickness: lockers tend to be made from a standard thickness of steel, which is commonly 0.8 mm. thick; but heavy-duty or high-security lockers are offered as a standard option by some manufacturers, or may be available on special order. A typical locker of this sort may be constructed from steel 1.2 mm. thick, for example, and is usually fitted with three-point locking, regardless of the number of tiers.
