From a Marketwired press release seen on Yahoo! Finance:
Canada’s most striking and legendary natural wonder, Niagara Falls, attracts tourists and adventurers from all over the globe. The Niagara Falls Marriott on the Falls has the distinction of being the closest hotel to this timeless natural attraction.
Using Google Maps geo data, the hotel with Niagara Falls views is a stone’s throw away, and is the Closest Hotel to Niagara Falls using Google’s line measurement technology. With spectacular views right from the hotel, the experience has to be seen to be believed. Guests booking Falls View rooms can lounge in the comfort and privacy of the hotel, witnessing the nearby falls in total comfort through floor-to-ceiling windows.
