Do a lot of searching on this Forum for Niagara for activities, campgrounds, restaurants, etc.
A couple of years ago we biked to the Falls, spent about an hour there, and biked back. It's one of those places that you visit, take a few photos, and tell everyone that you did it.
If you have time drive to Lockport and take a boat tour of the Erie Canal; at least as interesting as the Falls.
