Niagara Falls is amazing. I saw plenty of kids there this past weekend dragging their parents all around the place. A few things to do:
Canada:
Almost everything here takes American cash, so if you can't exchanged don't fret too much.
Must Dos:Get the Adventure Pass...DH and I were planning on not getting it until we realized that we wanted to do everything listed and if we paid seperately we'd be spending 30 more. It's also even cheaper if you order ahead online. Things that are included (all in Canada): Maid of the Mist, Journey behind the falls, White Water Walk, Niagara's Fury and 2 days transportation on the people movers (the bus that moves you EVERYWHERE). It also gives you half off the Spanish Aero Car and the butterfly exhibit.
Attractions:
Maid of the Mist: We saw kids begging parents to go again. The ship basically takes you past the American Falls and then out to Horseshoe Falls where it sits in the midst. You get these awesome rainbow views and it feels like it's raining (you get a poncho). My recommendation: Get of the top of the boat near the railing. It doesn't matter left or right, just get the top near a railing. The bottom is disappointing (DH and I rode three times

).
Journey Behind the Falls: You walk in a tunnel that takes you to (channels jungle cruise) the backside of water!! LOL, it's a great place to see this amazing white wall of rushing water. Then you get the chance to walk out to a little bridge and see the falls a few feet away. Don't worry they give ponchos.
White Water Walk: Amazing boardwalk besides the rapids. You get to litterally walk right up to class 5 and 6 rapids. The kids were standing right where the water squirts up and treating it like a water ride.
Niagara's Fury: this starts with a preshow: a little cartoon teaching us how the falls was formed. I kept feeling like it would really fit in in Disney. Then you go into a moving theater where you get to feel like you're riding the falls!!!
Spanish Aero Car: you ride out and look down at this huge whirlpool! It's very peaceful but the two kids on it were shocked. Don't worry about what side you're on, they switch at the end.
Butterfly Conservatory. I had to be dragged out. It's this HUGE area where butterflies of litterally every color swarm around you and circle you. One little girl said it best: I feel like snow white when she gets circled by the birds. The butterflies land on you and sit for a while and then fly off. It's one of the most magical places I've ever been.
That's all we did on the Canadian Side (we were only there 2 days and rushed through everything) If we'd had more time I would have made sure to see the Bird Kingdom. It's a FREE FLYING aviary. It looked awesome but also way too long. There's several other really awesome looking places, but I can't recall. You can probably find them easily.
But: If you're looking for a place to have dinner. I recommend driving inward. The food and prices near the falls just don't mix. I HIGHLY recommend Wildfire (6788 Thorold Stone Road, Niagara Falls, ON L2J 1B4, Canada). It feels like a real world Le Cellier and the steaks are just as good.
American:
We spent one day on this side...and wished we spent longer. There is SO MUCH TO DO. We did the movie (kinda dry for children, I wouldn't recommend) and the Cave of the Winds Walk. This was quite simply one of the most amazing experiances I have ever had in my entire life. I can't begin to tell you how it feels to be that close to a water fall. Once you stand under it

my word!! LOL!! I felt like a kid at a water park all over again! There were kids there dancing in the water spray and just jumping around excited. It was breathtaking. There aren't enough words in the english language to describe the place.
Lastly: I second Sheraton on the Falls. BUT Priceline it. It's much cheaper

. Feel free to PM me with further questions. Sorry for the book
