Remember too that there are two casinos in NF, the old (temporary!!??) Casino Niagara, and the newer and larger Fallsview Casino Resort which is directly across the street and connected by the walkway to the Hilton. The old casino is about a mile or so away from the Fallsview and the first you'll see as you cross the bridge onto the Niagara Falls, Ontario side.

Also since the OP is HH Diamond, be sure to request an upgrade to the king suite with the fallsview (if available), as I've found the hotel to be very accomodating with upgrades if it's not too busy. North tower suites also have jetted tubs although not they're heart-shaped. The Watermark restaurant on the 33 floor of the hotel has super views of both falls, and a good buffet style breakfast which should be complimentary with your Diamond status.
