The impending 2004 Republican National Convention seems to be falling short of expectations that it would give the city a much-needed economic boost, judging by the still easily available Broadway tickets and hotel room reservations.

A sampling of restaurants, hotels, Broadway shows, and nightclubs found a mixed bag as far as reservations go.

Hotels in Midtown near Madison Square Garden that usually require reservations months in advance are not yet fully booked.

As of yesterday, rooms could be still be had at the Crowne Plaza Hotel at the United Nations, the W Hotel, the Warwick and the Ritz Carlton-that is, if you’re willing to pay the price. A deluxe room at the Ritz will put you back $500 a night.

Broadway is also expecting lighter than usual business.

Although long-running major plays will keep their doors open, three shows – “Little Shop of Horrors,” “Frozen,” and “Caroline or Change” – are closing before the convention begins on August 30.

In addition, the Tony award winning one-man show, “I Am My Own Wife,” will be on hiatus during the week on of the convention, which runs through September 2.

Although delegates will be able to sample some of New York’s finest eateries, everyday New Yorkers might have to contend with simpler fare.

Most Midtown restaurants will remain open, but some, including the BB King’s Blues Club and Grill, will be closed to the public in order to host private parties for delegates and officials.

The upscale 21 Club plans to reopen its doors after its summertime closure to mark the arrival of delegates in the city.

Though no one will talk for the record, some businesses seem to fear the convention might bring as much good as bad. Citywide protests are planned, New York will be on an even more heightened terror alert, and navigating Midtown is expected to be a nightmare.

Neither the mayor’s office nor the city’s tourism office could be reached for comment.
