With someone else on hand to open doors, wash sheets, and wake you up in the morning, hotels render arms useless. Give shoulder limbs a well-deserved rest with today's Groupon. For $79, you'll get one night in a standard room at the Hyatt Regency Denver at Colorado Convention Center, a four-Diamond, centrally located hotel just minutes from the 16th Street Mall and the Denver Center for the Performing Arts. (This rate applies for a standard room with one king or two double beds.) You may purchase up to 10 Groupons for multiple nights or rooms.
