Our proposal has us using almost the entire convention space in the hotel (all but two boardrooms) plus around 30,000 square feet in the Buffalo Niagara Convention Center, which is across the street from the hotel. In the Convention Center, the proposal has us using North Hall on the Exhibit Level and rooms 103 and 104 on the lower level.
The current plan is to have Exhibits, Art Show, and Dealers room in the convention center, while Programming will be in the hotel convention space.
Note: the hotel and convention center are connected by an enclosed walkway over Pearl Street.
Here’s a map of the hotel convention space (PDF).
And here’s a map of the convention center. If you will look at the left side of the “Exhibit level” map, you will see that the walkway to the hotel connects directly to the North Hall.
