As you plan your sightseeing, consider these money-saving offers.

If you'll be in town for more than a day or so, pick up an Arts/Boston coupon book. It offers discounts on admission to many museums and attractions, including (among others) the Museum of Fine Arts, the New England Aquarium, the Kennedy Library, Massachusetts Bay Lines cruises, and Beantown and Old Town trolleys. It's not worth the money ($9) for single travelers because many of the deals are two-for-one, but couples and families can take good advantage. They're on sale at BosTix booths (tel. 617/482-2849; www.artsboston.org) at Faneuil Hall Marketplace (on the south side of Faneuil Hall) and in Copley Square (at the corner of Boylston and Dartmouth sts.), and by phone, Web, and mail.

If you concentrate on the included attractions, a CityPass offers great savings. It's a booklet of tickets (so you can go straight to the entrance) to the Harvard Museum of Natural History, the Kennedy Library, the New England Aquarium, the Museum of Fine Arts, the Museum of Science, and the Prudential Center Skywalk. If you visit all five, the price gives adults a 50% savings. At press time, the cost was $34 for adults, $$20 for youths 3 to 17; subject to change as admission prices rise, but still a great savings. It feels like an even better deal on a steamy day when the line at the aquarium is long. The passes, good for 9 days from the date of purchase, are on sale at participating attractions, at the Boston Common and Prudential Center visitor information centers, through the Greater Boston Convention & Visitors Bureau (tel. 800/SEE-BOSTON; www.bostonusa.com), through some hotel concierge desks and travel agents, and from www.citypass.com.

Even if you're visiting for only 1 day, the MBTA's Boston Visitor Pass (tel. 877/927-7277 or 617/222-5218; www.mbta.com) can be a good deal.
