Four local entities got great news from the White House yesterday: Their offers to host an event related to the G-20 summit had been accepted.

That left 296 others disappointed, or still holding out hope.

Some 300 venues and vendors submitted information about space and services they could provide for the meeting of world economic leaders, said Craig Davis, vice president of sales and marketing at VisitPittsburgh, which is coordinating G-20 events.

Applicants included hotels, restaurants, Downtown buildings, colleges and universities, cultural facilities, security firms, printing companies and culinary services. Mr. Davis' office collected the applications, put them in a binder and shipped it off to the White House in early June.

Then they waited.

Yesterday's announcement said events would be held at Phipps Conservatory in Oakland, The Andy Warhol Museum on the North Side, the Pittsburgh High School for Creative and Performing Arts Downtown, and Rosemont, the Fox Chapel farm of Teresa Heinz.

"Are we disappointed? Sure, but we also knew a lot of places sent information and the summit is only here for 36 hours," said Bill Schlageter, spokesman for the Children's Museum of Pittsburgh on the North Side.

In addition to the G-20 application, Mr. Schlageter said, the children's museum sent a letter to the White House inviting President Barack Obama and his family to visit.

Bill Laughlin, banquet manager for LeMont Restaurant on Mount Washington, said he submitted the facility's dimensions and seating capacity.

"I talked with the White House a couple times on the phone and I showed them the place when they came about three weeks ago," he said. "They haven't committed to anything, but it's still possible we'll hear something."

Betsy Momich, spokeswoman for The Carnegie Museums of Pittsburgh, said the organization had sent specifications for every event venue at all four museums -- art and natural history in Oakland and science on the North Side, as well as the Warhol.

"We were contacted directly by the first lady's office," Ms. Momich said. "They visited the Oakland building on the same day they visited The Warhol, looking for a location for a luncheon for the spouses."

Ms. Momich didn't know if the event at nearby Phipps would cause any disruption to the Oakland building, which also houses the music and lecture halls and the Carnegie Library's main branch.

"We haven't been asked to do anything in particular like changing our hours," she said. "I don't think anyone's gotten that far yet."
