613 N. Wells St., River North
Rate:From $67 for a private room (through February 28)
Details:That’s 15 percent off a no-frills room. And the same discount applies to drinks at the hotel’s karaoke bar, Blind Dragon, and its upscale restaurant, Mason.
20 E. Delaware Pl., Gold Coast
Rate:From $159 (through March 31)
Details:You have to stay at least four nights to land the 25 percent discount reflected in that rate, but you’ll also get a $25 credit each day (up to $100) toward valet parking or dinner at 20 East.
Waldorf Astoria Chicago
11 E. Walton St., Gold Coast
Rate:From $425 (through 2019)
Details:There’s a $100 property credit for each night you book a suite — which you can burn through at the hotel’s spa (lava shell massage, anyone?), its two French restaurants, or even just room service.
And one decidedly nonthrifty option for those who want to embrace the season with abandon:
323 E. Wacker Dr., Near East Side
Rate:$2,500 (Monday to Wednesday December 3 to 26)
Details:The Santa Suite, a.k.a. the 2,000-square-foot presidential suite dressed with 16 Christmas trees, comes with an in-room hot chocolate bar for the kids and Champagne for you. (A visit from the bearded guy costs an extra $200.)
