Our pick for a super-chill culinary experience: Sip Champagne and dine on seasonal and locally sourced dishes inside “ice domes” at Four Seasons Hotel Washington, DC’s Bourbon Steak restaurant. As part of the 220-room hotel’s annual wintry transformation, November 12 through March 12, Bourbon Steak builds three six-person, heated domes, each outfitted with chic throws to keep diners extra cozy. A plus for families: Kids can order s’mores and hot chocolate, and later, sleep “under the stars” in their room in glow-in-the-dark, domed tents. At the hotel’s spa, self-care aficionados can treat themselves to a winter-themed spa treatment designed to rejuvenate cold-weather skin and reduce inflammation, while at ENO Wine Bar, connoisseurs can taste a selection of ice wines. Virtuoso travelers receive breakfast daily and a $100 spa credit.
