When Seneca Niagara Resort & Casino wins: pick Seneca if you want 24/7 casino action, more on-site dining and bars, free self- and valet parking, larger meeting and event capacity, and a property geared to both families and adult nightlife.
When Marriott Niagara Falls Fallsview Hotel & Spa wins: choose Marriott Fallsview if you want a polished, branded Fallsview hotel experience with a dedicated full-service spa, indoor pool and hot tub, concierge and limo/town-car services, and proximity to Canadian-side attractions.
