There's a line in the movie "Diner": "Didja ever get the feeling there's something going on that we don't know about?"

Well, the second annual "Suite Life" tour is our chance to check it out.

The day of rubbernecking at posh suites in five local hotels offers a window on how the other one percent lives -- and benefits the nonprofit League of Washington Theaters.

The tour, which runs Saturday from 10 till 6, visits one of the chic suites in the brand new, all-suite Bristol Hotel; the Vista International's five-room Presidential Suite (designed by Givenchy and featuring a view of the city from a window wall); the Watergate's two executive suites; the Capital Hilton's redesigned State Suite (with the Harry Truman grand piano); and two Shoreham suites, including the Mark Russell Suite that's been home away from home to many celebrities.

Participants will be chauffeured from suite to suite in tour buses, or may walk at their leisure. Wine and hors d'oeuvres will be served; a complimentary book of discount coupons for area hotels, restaurants and theaters is included.

Tickets cost $12 if bought Friday, available by phone charge (499-1800). On the day of the tour, they'll cost $15, available only at the Shoreham Hotel, 2500 Calvert Street NW. Call 338-0948.
