You could even hear the Falls if you were standing right next to the window. We got in kind of late, so we didn't do anything the first day except go out to dinner and watch TV in our room. So relaxing and fun!
The next day we lounged around for quite a while, then walked around town a bit. We went to see the IMAX show about the history of Niagara Falls which I thought would be super cheesy. It was, I guess, but it was also good enough that we brought it up constantly for the rest of our trip. It was mostly about the people who've tried to go over the falls in barrels and other contraptions, aka Crazy People.
On Monday, we took a city tour which was good. We went up the big observation tower (of course!). Our driver took us down the river to where the huge rapids and giant whirlpool are, though they're not that scary right now since most of the river is frozen. Apparently in the summer, it's incredibly dangerous.
It was a great trip and a fun way to celebrate our anniversary!
