We walked through this Casino and FallsView Casino. Casino Niagara was just as nice, but it was hard to tell if it was as crowded...the casino was on three different floors! Here's a great tip for you if you're staying at a different hotel along Ferry or Victoria Drive.
When staying at any of those hotels, you'll walk down hill to the falls. Coming back up was no problem for us, but it can be a steep climb back to the top.
On our last night, we were down shopping by the falls at the Hershey store. We cut through Casino Niagara, took the escalator up to the third floor and then went out the casino, bypassing that steep climb back up from the falls! We needed that after a long day of walking!
