There are also 2 Marriott's over in the Fallsview area. One, the Marriott Gateway is the old Sheraton Gateway. The Marriottt on the Falls, is across the road, right next to, the old Minolta Tower (which is now a hotel itself). My personal preference would be the Embassy Suites, closest to the rim of the falls, unobstructed views along the river up and downstream of the falls, and the incline railway is connected to the hotel by a walkway over Portage. Groupon, Wagjag and similar sites have tons of Niagara hotel deals on them.
