Situated in Bostons hip Back Bay neighborhood, the upscale Colonnade Hotel is home to the citys only rooftop pool, a glamorous urban oasis with impressive views of the Boston skyline. By day, sunbathers recline on lounge chairs sipping frozen daiquiris. In the after hours, the place comes alive with sunset cocktails and live music. From now through Labor Day, guests can enjoy the rooftop atmosphere with unseasonably low hotel rates. Book a two-night weekend stay with the Summer Meltdown special, and pay less the higher the thermometer climbs. Rates start at $269 minus the temperature on the first night of your stay, and $269 on the second night. Hope for long hot days and dont worry if you forget your SPF at home sunbathers receive free samples of Shiseido sunscreen from now through September 6.
