Sometimes you just don't know what your schedule will be until the very last minute. At that point, if you try to book a quick getaway, all you can do is hope that all the good rates aren't taken. The new Starpicks program allows you to be spontaneous and save some money at the same time. When you visit the site on Tuesday through Friday, you can book a hotel for the coming weekend or a room at a resort for anytime in the next two weeks. Not only that, but you'll save at least 20% off the regular rates. There's an added element of excitement to this program as well: the participating properties change each week, so checking back every week could lead you to new vacation destinations you may not have considered before. One such hotel is the Sheraton San Diego Hotel & Marina, a waterfront property with pools, tennis courts, jogging trails, and (your reward) a spa. The spa offers massages, facials, and body treatments, the better to primp before heading out to one of the hotel's six restaurants. There's plenty to do at the hotel, but you'll want to visit the rest of San Diego as well, of course. The San Diego Zoo and Sea World are both nearby, and the historic Gaslamp Quarter is also close to the hotel. The Sheraton offers bicycle rentals, so getting to any of these destinations is a breeze.
