I just booked our hotel stay at the Hilton. I had a great casino offer with 50$ a night casino credits. We are going to walk around by the falls (where he proposed), Clifton hill like a bunch of goofs, casino, eat and lots of rest.
I live in Niagara so won't be honeymooning there. If you are bringing the whole family great wolf lodge is great. I go every year. From there you can get a bus that takes you to all the amusement things in Niagara. Clifton hill has a lots of things for the whole family.
We looked into it. But changed our minds to Montreal. But there is special all access pass you can get that gets you into different rides and attractions like mini putt, the ferris wheel, the wax museum ect. We were also going to do the Ripley's museum. I would also recommend great wolf lodge if you like water parks.
