As Pittsburgh hotels all but burst at their mortared seams with dignitaries and media associated with the upcoming G-20 summit, proprietors of overnight accommodations in the suburbs are licking their chops at the spillover business -- as are some of the guests of one particular hotel property.

Indeed, more than 50 high-credential government agents -- agents with chops worth licking -- have been booked into rooms at the Pittsburgh Marriott North in Cranberry where they will be greeted with some special doggie bags that are literally for the dogs.

Dogs, as in Secret Service dogs.

More than 50 dogs that are part of a 150-person Secret Service contingent are among the capacity crowd that's expected through Sept. 25, said General Manager Ron Antonucci.

The federal canines are receiving welcome doggie treats and plastic bags for "cleanup." Their handlers and the rest of the federal team will receive milk and cookies.

"We wanted to do something fun for them. What we've come up with will be cute and fun and accommodating yet practical, too," Mr. Antonucci said.

He said his 295-room property is near capacity during the summit. In addition to the Secret Service crew, some 20 Spanish media members will be staying at the hotel, which is about a 20-minute drive from Downtown Pittsburgh.

Mr. Antonucci said the extra business has boosted the normally busy hotel to fully booked as well as to premium pricing levels. "The laws of economics have kicked in and we're liking the opportunity it presents," he said.

Jeffrey Stein, managing director of the Four Points by Sheraton Pittsburgh North, said the conference overflow from Pittsburgh has crept up the interstate to his 189-room property in Marshall, though he declined to specify who's who among his prospective guests for fear of spillover protesting.

"There's definitely compression from the crowded Downtown scenario, to the north, the airport corridor and the Monroeville corridor," he said.

Mairead Hennessy, general manager of the Hyatt Regency Pittsburgh International Airport, declined to give specifics but noted that "two smaller (governmental) delegations" are among the guests filling their 336-room property in Findlay, as well as two other conference-associated groups.

"We're fully committed at this point and we were pretty confident we would be," she said, noting that her counterparts at other airport corridor hotels had expected G-20-related bookings.

"Normally, the airport corridor does a little better than Downtown Pittsburgh and we're among the higher occupancies within that corridor. With the conference being held Downtown, we expected to do well," she explained.

The same is true for the Monroeville corridor, to the city's east, said Donald K. Schultz, general manager and director of sales for the Comfort Suites-Monroeville.

"Monroeville is virtually fully booked," said Mr. Schultz, who said he has "daily contact" with his counterparts at the properties within his corridor.

At his 40-room boutique hotel, about 25 percent of his guests during the conference period are related to the G-20. "They set aside a block of rooms long ago. The rest filled up with our usual corporate clients," he said, noting that full occupancy is the norm for his property.

Duane McKee, assistant township manager for Cranberry, said municipalities around Downtown Pittsburgh have an opportunity because of the conference to reap some financial benefits.

"They've got to sleep somewhere. They've got to eat somewhere. And not everyone can fit in Pittsburgh. We see this as an opportunity to share Cranberry's success story with even more people."

And dogs, too.
