Siemens has a significant presence along Colorado's Front Range, and Denver trips for project coordination, client meetings, or conferences at the Colorado Convention Center are common. Corporate code 104256 gets you a negotiated rate at this downtown Holiday Inn Express, saving real money on what would otherwise be a $200+ nightly stay. The included breakfast and IHG points earning make the per diem math work even better.
The Property
The Holiday Inn Express Denver Downtown sits at 1715 Tremont Place, right on the edge of the central business district and about a 10 minute walk from Union Station. The neighborhood is walkable, with restaurants, breweries, and coffee shops within a few blocks along 17th Street and Larimer Square. Denver International Airport is roughly 27 minutes by car or about 37 minutes via the A Line commuter rail from Union Station.
Rooms at this Holiday Inn Express are compact but functional, typical of the brand's urban format, with a work desk, ergonomic chair, and reliable Wi-Fi included at no extra charge. Expect standard kings and double queen configurations, with some suites available for longer assignments. The mattresses are IHG's standard bedding package, and every room includes a mini fridge, microwave, and Keurig coffee maker.
The complimentary Express Start breakfast is the standout here, covering eggs, bacon, pastries, fruit, and pancakes every morning, which saves $15 to $20 per day versus eating out downtown. There is a small fitness center on site for basic workouts. The hotel does not have a pool, restaurant, or airport shuttle, so plan accordingly for DEN transfers.
The Colorado Convention Center is about a 12 minute walk south on Tremont, and the 16th Street Mall free shuttle bus runs just a block away for getting around downtown without a car. For dinner, Rioja and Guard and Grace are within a 10 minute walk and both handle business dinners well. Union Station, with its A Line train to DEN and several solid restaurants inside the hall, is a straight 10 minute walk northwest.

Stack Your Savings
If you hold IHG Platinum Elite or higher status, your benefits apply on top of the corporate rate. That means room upgrades when available, late checkout, welcome amenity points, and bonus point earning of up to 100% extra. Even Gold Elite members get a 10% bonus on base points, turning that 1,790 into closer to 1,970 points per night.
The IHG One Rewards Premier Credit Card from Chase earns 10x bonus points on IHG purchases, effectively doubling your earning to around 3,580 points per night at the corporate rate. If you carry the card, you also get automatic Platinum Elite status and a fourth reward night free on award stays, which makes redeeming points significantly more efficient.
IHG regularly runs quarterly promotions like bonus points after a set number of stays, or double points on weekend nights. Check the IHG app's Offers section before your trip and register for any active promo. Booking a few weeks out rather than last minute also tends to keep corporate availability open, as allocation can tighten during peak convention weeks in Denver.
Bottom Line: Depending on the season and how far in advance you book, Siemens code 104256 can save you anywhere from $24.55 to $65.45 per night at the Holiday Inn Express Denver Downtown after factoring in points value. It is a practical, no frills base for downtown Denver business trips, with free breakfast offsetting meal costs and a location that keeps you close to the Convention Center and Union Station. For Siemens travelers who want to keep expenses reasonable without staying out by the airport, this is the right call.
