"Boasting panoramic city views in the heart of Dupont, the Ven at Embassy Row hotel invites guests to splash around from 9 a.m. to 5 p.m. Frozen Delola spritzes for summer join poolside snacks like shrimp cocktail and nine-inch pies. A heated pool offers food and drink service, and its Tag Rooftop Bar swings open at 4 p.m. Accessible to hotel guests or day pass holders (starting at $40) with cabanas starting at $250. The pool is also the place to be on Sundays this summer for its once-a-month “Splashy!” DJ series (the next one is July 27)." - Tierney Plumb
