Traveler’s Notes

Frommer’s has published its first “California From $60 a Day” guide (Macmillan Travel, $18.95 paperback). That’s $60 total, per person, for lodging and three meals; costs such as sightseeing and transportation are extra. . . . This summer, for the first time, the New York Historical Society is offering Central Park tours on Fridays, Saturdays and Sundays through Aug. 31. The $8 fee includes admission to the society’s museum and, at 2 p.m., a 90-minute park walk. Tours start at the society headquarters, 2 W. 77th St. Information: tel. (212) 873-3400. . . . The U.S. Virgin Islands this month changed its telephone area code to 340 from 809. Both codes will be accepted through June 30, 1998. . . . Swissair flights originating in Zurich and Geneva now offer organically grown food in breakfasts and hot meals, in all classes; salads and snacks will go organic later. Swissair claims it’s a first.
