Summer Deals: D.C. Hotel Packages

Cool drinks, steamy rooftops—must be a sweet summer of hotel options in Washington.

No matter the temps, the rooftop at the Liaison Capitol Hill (affinia.com) is one of the best spots in town. You’ll love the pool, cabanas, DJ and food from Art and Soul. Early birds: Don’t miss rooftop yoga at 7:30 a.m. Mats, bottled water and towels provided, reservations required.

If you haven’t seen the fireworks display from the roof of the Hay-Adams (hayadams.com), you haven’t really celebrated the Fourth. Check out the hotel’s holiday package, which includes accommodations the night of July 4; a three-course dinner with wine and open bar; and access to the Top of The Hay for fireworks viewing, open bar and desserts. Rates begin at $1,070.

Brabo Tasting Room at the Kimpton’s Lorien Hotel & Spa (lorienhotelandspa.com) in Alexandria hosts Toast on the Terrace every Thursday until fall. Bottomless sangria and heavy hors d’oeuvres! From 6−8 p.m., $40 per person.

A portion of the proceeds from the booking will be donated to the National Museum of American History. Available on Thursdays, Fridays and Saturdays through 2011, $509 per night.
