Just got back from the Niagara Falls Embassy Suites, VERY nice! Be sure and check the type of room you reserve, it is very confusing between premium fallsviews and regular fallsview, that is the floor you are on, not the view. The view of just the Canadian Falls is not nearly as nice as the view of both American and Canadian (both labeled as Premium Fallsview with different prices), and the fireworks can only be seen from that side of the hotel if you want to watch them from your room. We reserved the Canadian side and were very pleased they upgraded us to a view of both falls.
The managers reception was only so so, we were disappointed not to have the typical inner courtyard associated with Embassy Suites, but can understand why they don't do that in this location. The breakfast was a regular buffet at the TGIF connected to the hotel and was very nice. All in all, a great stay, would definitely go back, but have no experience with other hotels in the area to compare. BTW, the construction next door had zero impact on our stay, view, etc.
