Amenities are in all rooms unless noted otherwise. Seneca Arrival Experience is what the project has been named. When guests arrive from the Robert Moses Parkway they will be able to see a dramatic change to the exterior. The casino is located next to Niagara Falls. LARGESTROOM: 24443.00 The initial phase of the multi-year development began with the fast track conversion of a 1974, Philip Johnson designed, under-utilized 400,000+ square foot convention center, into a class III casino. This first phase included an 82,000 sf gaming floor with 2,595 slot machines and 91 table games, a center bar, 350-seat “Thunderfalls Buffet,” casual dining, the “Bear’s Den” 440-seat showroom theater and back of house space. The entire project was designed and constructed within a lighting-fast timeframe of just 100 days, and came in at 12% under budget.
