Feel like a plush holiday getaway in the big city right about now? The Ritz-Carlton Chicago, located on the Windy City's Magnificent Mile, offers lush rooms and suites with marble bathrooms, twice-daily housekeeping service, and a full-service spa.  Families are welcomed into the mix with an indoor pool, babysitting services, complimentary baby gear (think bottles, strollers, diapers), special in-room amenities for kids, and the option for an in-room campout with a kids' tent and s'mores. This month, the hotel rolls out the red carpet for the holidays with dive-in holiday movies and cookie-baking for the kids. Also on the table through December 31: a Third Night Free offer.

The offer lists starting nightly rates of $233 after the third night credit is applied. The room rates are the same with and without the offer, which means this is a straightforward 33% savings.  We found a superior room—the least expensive room category—with a nightly rate of $350 in December. With the third night free offer, a three-night stay will cost $700 instead of $1,050, effectively reducing the nightly rate to the advertised $233. 

Got an only child? This offer is right up your alley. For the rest of us, not so much. The Ritz's least pricey rooms are limited to families of two adults and one child under 18.  A family of four would have to book a suite, the least expensive of which is an executive suite at $495 a night.  With the offer, the tab would come to $990 instead of nearly $1,500, bringing the nightly rate to $330. But that's still nearly $100 more a night than the superior room category.

Even though this offer does translate into savings of a solid 33% off regular room rates, families of four or more will still pay a minimum of $330 a night. Yet if you're looking for an upscale family city getaway, this promo does deliver it for less.  Restrictions apply; book online or call 800/621-6906 and ask for the "Third Night Free" offer.
