Niagara Falls Marriott Fallsview is probably one of the best hotels locationwise at Niagara Falls. You could spend the entire day overlooking the falls without even leaving your room.

We were satisfied with our stay with one exception - the dining accommodations!
I have stayed at thousands of hotels and a lot of them belonged to the Marriott chain but this was the first time when I was told that I could not pay for breakfast - a la carte and take it to my room to my kids. I was told that I should either use room service or sit down for continental breakfast. I requested that I speak to the manager on staff for the dining room- November 24th - and she was extremely rude and unaccomodative. So my recommendation would be - even though this is a great location it probably is not suitable for people with young kids.
In addition, I had sent a couple of questions to the hotel prior to our trip and I never heard back from them - which I also find a bit peculiar.

My fiancé and I got engaged and decided to take a two night romantic package. We want in March still cold but nice enough to walk around and see the sites! Dinner and king size bed with big tub, and a bubble bath with champagne! Perfect for a engement celebration!
