Fallsview Waterpark (fallsviewwaterpark.com) in association with the Sheraton on the Falls, Brock Plaza, Skyline Inn (all indoor connected) and the Hampton Inn which is across the street. Pretty good waterpark... no lazy river I think. Good if you are part of the Sheraton rewards program or Hilton rewards program though. Americana Hotel (americananiagara.com). Motel with indoor waterpark... smaller waterpark, not as large variety of slides...wave pool and water playhouse. Least expensive.
