Stayed one night in December 2012 in a full falls view room. I heard there are rooms with only partial view of the falls. It's important to get a full view room to enjoy the stay! It's breathtaking and the falls, mist and if you are lucky the rainbow are continuously changing!
Rooms are quit spacious and with 2 king size beds! Can accommodate 4 persons! We could get a highly discounted online price. Breakfast/ Wifi were not included. Parking cost additional 25 CAD. Didn't use SPA.
Tip: If you have a car, it's highly recommended to drive around in the area to see the light displays in the night and the beautiful village of Niagara on the Lake!
