Go coastal this summer and head south of the border to Acapulco, the oft-overlooked Pacific Coast retreat nestled between the soaring mountains of the Sierra Madre on one side and the crystal blue bay on the other. Book a stay at the premier resort in the area, the Fairmont Pierre Marques, once the private getaway of J. Paul Getty, and enjoy fantastic savings with "Only One Way" summer rates, starting at just $149 through early September. With refreshing infinity pools overlooking the ocean, a state-of-the-art fitness center, tennis, golf, and aquatic sports galore, this landmark hotel offers endless fun in the sun for a real steal. (The hotel's sister property, Fairmont Acapulco Princess, has likewise reduced its summer rates.)
