Scoop up half-price rates at the 2-year-old Alexander Hotel on Cayman Brac, a 12-mile island off the coast of Grand Cayman. The boutique hotel sits on a salt water lake and has a courtyard pool surrounded by sand to give it a beachy feel (pristine shorefronts are only a few minutes from the hotel). Slick rooms come with full kitchens and free Wi-Fi. The booking details for this deal seem unnecessarily complicated, but heres the gist: Book a deluxe queen or a deluxe twin between Thursdays at midnight through midnight on Saturdays, now through September 6, to snag discounted rates of $72/night (down from $157/night). Travel is valid this July through September 30.
