Head to D.C. in autumn for mild weather without the blossom-thirsty throngs. For $109-$129 per night, settle in just across the Potomac in Arlington and save up to 50% on rates for surrounding dates for Friday-Saturday stays December-January.

Overlooking the Pentagon, the Sheraton Pentagon City Hotel is three Metro stops or a short drive from the National Mall and its 10 Smithsonian museums. In Pentagon City, browse shops at the Fashion Centre, or visit Pentagon Row for a range of restaurants and outdoor ice-skating into the evening.

After a day of sightseeing, savor a meal or cocktails in the onsite restaurant or hit the fitness center.
