In Denver I would have four different options for you - the Brass Renaissance Resort for 10 days (a three star hotel with 8.86/10 guest rating) from Sept 13-21, Solar Inn for 10 days (a three star hotel with 8.69/10 user rating) from September 15-23, or 8 days from Sept 12-18, and lastly the 3 star Oriental Resort (unrated by users) is available for a nine day stay from Sept 13-20.
